PR = proof - a coin produced from polished dies and/ or planchlets. Most often each proof coin is struck twice/ or more which gives the coin a very sharp degree of detail and mirror like surface. Proof coins are usually made for numismatic purposes, presentations, or souvenirs. Proofs are usually not made to circulated in commerce. Mishandling can lower the value and grade of a proof coin. Proofs are sold by the mint during their year of production at a premium to cover their special manufacturing costs. Sometimes sold only in sets. * Proof Gold coins...made of pure gold. These are used to test and make comparisons during the coin assaying process. By having samples of pure precious metals available mint assayers can accurately test coins for correct purity. Most 'proof silver ' and 'proof gold ' pieces are made at the Philadelphia US mint and supplied to the other mints and government assay CAM = cameo -a coin with a cameo design will have a somewhat frosted appearance to the raised features of the design, with a polished or mirror like background (field). DCAM = deep cameo - describes the appearance of some proof coins. A coin with a cameo design will have a somewhat frosted appearance to the raised features of the design, with a polished or mirror like background (field). Deep cameo means this frosted cameo effect is very obvious. Often, a proof with this attribute will be of higher quality and may be rarer, particularly in older proof coins. |
