Proofs take a variety of forms and represent the progress of the creation of the final stamp image. Die proofs of the unfinished design ("stages") can show the work of the engraver as it progress, while the final die proof shows the finished engraving. Because die proofs are typically pulled from the actual original engraving, the impression quality is typically superior to that of the issued stamp. A "sunken" die proof has the die impression in an embossed area that "frames" it. Color proofs are experiments or trials to determine which color(s) best present the image. In the case of multi-colored stamps, slightly changes in the combinations of colors can make dramatic differences in the final stamp image.
Discussions with experts on proofs of Monaco and the "French area" have given me the following understanding...
Monaco die proofs were prepared in two types: "final" and "stage" (unfinished design). Typically about 19 final die proofs are prepared; of these more are black (typically 10) plus perhaps 3 each of 3 other colors. The die proofs are normally single color. Some examples, at least of the black, usually exist in private hands. The "stage" die proofs, at least as officially released (i.e. other than proofs prepared by the engraver to check on progress), typically exist at only a single stage of the engraving process; typically only 3 "stage" die proofs are prepared (and may or may not exist in private hands).
Plate/Color proof sheets were prepared of both the stamps issued in sheets of 10 (usually the larger-format stamps) and the sheets of 30 stamps. The sheets of 10 are typically printed on a 6-color press, while the sheets of 30 stamps are typically printed on a 3-color press. It appears that typically 13 different proof sheets were prepared; each of the 13 contains different colors and/or combinations of colors, thus each of the 13 sheets would typically look dramatically different. It seems that only ONE of each of these 13 proof sheets exists/existed in private hands (and many have been broken up over the years). The proof sheets of 10 stamps typically contain all-different colors or combinations of colors, thus each individual proof may be unique in private hands! The proof sheets of 30 stamps for single-color stamp issues typically repeat only the 3 single colors (they were printed on a 3-color press) and do not include color combinations; because of the 6-row by 5-column configuration and the way the colors are used, typically one color exists in 6 more examples than the other two colors. The proof sheets of 30 stamps for multi-color stamp issues typically contain 6 sets or 3-strips of 3 single colors, plus an additional 6 examples of one of the single colors, plus typically 6 2-color or 3-color combinations. Those particular color combinations thus typically appear to be unique in private hands.
Monaco is one of the few "Slania countries" from which any form of proof material is available to collectors. Such material is completely legitimate, usually bearing an official control imprint (some issues exist without the marking, but seem to be much scarcer in that form), often being presented to government officials or other dignitaries, or being sold on behalf of the postal museum. Proofs of Monaco Slania-engraved stamps are scarce and very much sought after.

Scott #974 [1975 European Architectural Year; National Museum] imperforate color plate proof complete sheet of 30 in experimental colors. The extreme lower right corner (far away from the stamps) is thinned, but is of no consequence to the value of the sheet. The top four rows are in single colors; the colors are very close to the final colors used (in combination) for the issued stamp. Each of the first four rows is all the same color, in order from top: light blue, green, brown, and brown again. The stamps in the bottom (fifth) row, are each different three-color combinations. The colors of the text at top and/or bottom, tree, building components, groundcover at bottom, etc. all vary differently. The lower right stamp uses the same color combination/usages as the issued stamp, however, the blue and green are slightly darker on the issued stamp. Based on my understanding that there is only one proof sheet of any particular "color set" in private hands, this means that only six sets of the three single colors exist (plus six extra of the brown) and the six combinations are unique in private hands. This sheet does have the usual oval control imprints on the reverse. This stamp issue relates to a couple popular topics/thematics, including Europa. Based on long experience with Slania-engraved Monaco proofs, the break-up value is in excess of $2900; perhaps higher due to the thematic appeal.

Scott #991 [1975 2.00 fr Prince Honore III] imperforate color plate proof complete sheet of 10 in experimental colors. In the "Princes" issue, the typical proof sheet arrangement consists of the first stamp in the top row showing the background colors (all the colors are engraved which again proves that Slania was a master), followed by four dramatic proofs showing combinations of foreground colors and (sometimes quite odd) partial background colors. The bottom row typically contains complete foreground and background color proofs, but with various, often subtle color combinations, especially in the color shades of the costumes and the colors of the text at top and bottom. Sometimes the text color differences are hard to see in a picture. Typically one of the bottom-row stamps looks very much like the issued stamp, though there are usually still small differences. Such proofs sheets are usually wonderful "riots of color" that showcase the skill of the master engraver, Slania. Based on my understanding that there is only one proof sheet of any particular "color set" in private hands, each of these proofs could be unique private hands. This sheet does have the usual oval control imprints on the reverse. All ten stamps are obviously different. Based on long experience with Slania-engraved Monaco proofs, the break-up value is in the $1500-1750 range.

Scott #1416 [1984 3.00 fr Clerissi Sketches of Old Monaco] imperforate color plate proof complete sheet of 30 in experimental colors. All stamps are in single colors; the issue was conceived as single-color stamps. The single-color columns are, in order from left: purple (VT308), olive green (BR605), and carmine (RO211), followed by purple again. The stamps in the right (fifth) column, twice sequentially repeat these three colors in reverse order. Based on my understanding that there is only one proof sheet of any particular "color set" in private hands, this means that only eight sets of the three single colors (plus six extra of the purple) exist in private hands. This sheet does not have the usual oval control imprints on the reverse (quite unusual without the marking). Based on long experience with Slania-engraved Monaco proofs, the break-up value is in excess of $2500.

Scott #1417 [1984 6.00 fr Clerissi Sketches of Old Monaco] imperforate color plate proof complete sheet of 30 in experimental colors. All stamps are in single colors; the issue was conceived as single-color stamps. The single-color columns are, in order from left: blue (BL405), ultramarine (BL408), and violet ultramarine (BL411), followed by blue again. The stamps in the right (fifth) column, twice sequentially repeat these three colors in reverse order. Based on my understanding that there is only one proof sheet of any particular "color set" in private hands, this means that only eight sets of the three single colors (plus six extra of the blue) exist in private hands. This sheet does not have the usual oval control imprints on the reverse (quite unusual without the marking). Based on long experience with Slania-engraved Monaco proofs, the break-up value is in excess of $2500.

Scott #1462 [1985 2.10 Stamp Exhibition and 100th Anniv. of Monaco Stamps (stamp on stamp design)] imperforate color plate proof pair in individual experimental colors: bright blue and bright green. Mint hinged. On reverse has the expected oval control imprints and penciled notations that may be the color codes for this proof. A rare proof from a stamp issue for which unusual material is very rarely seen; I have not had any other plate proofs for this issue.

Scott #1607a-c [1987 Philatelic Bureau, three designs] Set of three matching sunken die proofs in Dark Brownish Maroon, with postal museum handstamp on reverse. This set of proofs is known, but seems to be extremely scarce. As of 2/10, I am aware of two other sets in private hands, but this is the only set I have ever seen.

Scott #1665 [1990 2.30 Rainier] Imperforate color plate proof pair in two different single colors on rose surface-printed paper. Stamp colors of this pair (left to right): violet and bright ultramarine. From a 5-strip with stamp colors (left to right): violet, bright ultramarine (bu), bu, violet, bu. The pattern of colors may or may not have been the same throughout this proof sheet; it is also possible (likely?) that a third color may have been used in part of the proof sheet. (The issued stamp was printed in brownish red on rose surface-printed paper.) Without a Monaco Philatelic Museum handstamp on reverse; scarcer thus. Proofs of the definitive issue stamps seem to be much scarcer than those of commemoratives.

From a strip with stamp colors of (left to right): bright green (bg), yellow brown, ultramarine (u), bg, u. The pattern of colors may or may not have been the same throughout this proof sheet. (The issued stamp was printed in dark green on greenish surface-printed paper.) Without a Monaco Philatelic Museum handstamp on reverse; scarcer thus. Proofs of the definitive issue stamps seem to be much scarcer than those of commemoratives.

Scott #2086-9 [1998 Cactus set: 2.70, 4.00, 6.00, and 7.00 values] Imperforate color plate proofs singles. The stamp designs are each complete and each in a different single color (instead of each being multi-colored). This matching set is from plate position 7, showing "Valeur" in the bottom margin; inscriptions are in varying colors. Stamp design colors and marginal inscription are as follows: 2.70 red, green; 4.00 deep red, deep red; 6.00 dark green, red; 7.00 bright green, red. Without a Monaco Philatelic Museum handstamp on reverse; scarcer thus. Proofs from this later era are much scarcer than earlier.

Scott #2214 [2001 Oceanography] imperforate color plate proof single in an experimental color: brownish orange stamp design with sheet margin inscription in black. NH VF. On reverse does not have the usual oval control imprints. Plate proofs of any of the very modern stamp issues are extremely scarce. This one also has very strong thematic appeal.
