Hi guys...I have a couple New Brunswick proof plates..As you can see from the pictures below, I have a hard time understanding the difference between PROOF plates and DIE plates...I have what I think are a Scott #10P and a Scott #11P...But there are 2 different kinds as you can see in the charts below..HELP.
Wert, Start by correcting your nomenclature. What you are referring to are Die Proofs, Plate Proofs, and Trade Sample Proofs. Die Proofs are made from the actual die that is used to make the transfer roll that is used to impress the images into the plate. Die proofs are usually single impressions on varying sizes of paper. Occasionally you can have a compound die proof with different images printed on the paper. Plate Proofs are from full printed sheets made from the plate that is actually used in printing the stamps. Trade sample proofs are made from the original dies and used for favors or advertising to promote the printers work. This is just a short simplified break down on these but will give you an idea of what they are.
The normal printing process during that period was to engrave a "die" which was a single example of the stamp and then take proof impressions to check the quality of the engraving. Once satisfied with design, the printer would prepare a transfer roll and then use the transfer roll to layout a printing plate - say a sheet of 100. Proof impressions taken from the plate are plate proofs. Proof impressions from the die are die proofs. Die proofs are normally single impressions on a piece of paper that is much bigger than the stamp design. However, die proofs are sometimes cut down to near stamp size. If a proof is known as both a die proof and a plate proof, you have to assume that it is a plate proof if the margins are smaller than the space between stamps on the plate, unless it is otherwise possible to distinguish the proofs based on the type of paper or ink color. Without knowing anything about New Brunswick proofs, I would assume your examples are plate proofs with sheet margins at bottom.
