Proofs take a variety of forms and represent the progress of the creation of the final stamp image. Die proofs can show the work of the engraver as it progress or final die proofs can show 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 usually "experiments" 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.
Monaco is one of the few "Slania countries" from which any form of proof material is available to collectors. Such material is completely legitimate, bearing an official control imprint, often being presented to government officials or other dignataries, or being sold on behalf of the postal museum. Proofs of Monaco Slania-engraved stamps are scarce and very much sought after. All items are VF and fresh. If you are seeking this type of material, please let me know of your interest; such items seldom make it into my price lists. I am always interested in buying such material.
