devoted to it. Here is one final, very important similarly between the Morgan coin dollar cleaning series and the Cameo Proof series: In grading prooflike Morgan dollars, the two largest grading services in the nation, PCGS (Professional Coin Grading Service) and NGC (Numismatic coin Guaranty Corporation), offer two grades of prooflike for that series - "DMPL" (Deep Mirror Prooflike) - for cleaning the very earliest strikes off the business die, and a simple "PL" (Prooflike) - for the slightly later coin and cleaning strikes. PCGS and NGC now offer a similar delineation for all proof coinage from the 1950 to 1970 era. As of early coin February, 1992, PCGS offers two cameo designations for early strike cameo proofs - "DCAM" (Deep Cameo - roughly equivalent to what we refer to as "ultra-heavy") - for those cleaning cameo proofs which were the very earliest strikes off the proof die, with the heaviest contrast, and a simple "CAM" (Cameo) designation coin for those coins which were slightly later strikes, but which still possess significant cameo contrast. NGC instituted their own cleaning two-tier coin system cleaning similar to PCGS'' in the spring of 1995. coin With PCGS and NGC now involved, novices will for the first time have their coins recognized by the most widely used grading service in

involved "acid-dipping" the dies before they were polished. The solution used during the 1950 to 1970 period, a bath consisting of 5% nitric acid/95% water, was used to create an acid-etched appearance on the die. When the die was subsequently polished and buffed, the recessed portions of the die, the devices, retained their acid-etched cleaning and coin cameo. The very first strikes off one of these new dies would possess a gorgeous, intense cameo effect very cleaning similar in quality to the proofs minted today. The raised portions of these early strikes, the coin devices (on the Franklin half, these would be the bust of Franklin, cleaning the coin lettering, and date on the obverse, and the Liberty bell, eagle, and lettering on the reverse) would display a snow-white cameo effect that would stand in stark contrast to the deep-mirrored fields surrounding them. The flawless, jewel-like quality of the best of these cameos almost look like works of art rather than mere coins! Indeed, to most collectors, these coins are works of cleaning art! The frosted devices of these early cameo dies were quite delicate - one could easily scratch a bit of frost from the die with one''s fingernail, and were the first part of the die to wear. Each
