Acronyms used in Coin Collecting

This list is intended to cover the acronyms which are commonly used in the internet newsgroup rec.collecting.coins . For completeness, it includes mintmarks, internet phrases, and a few abbreviations (like UNC). I have been informed that true acronyms are pronouncable, such as MASH, WAC, RADAR, etc., so perhaps the items below are more accurately described as "initials". All references are to United States coins, unless otherwise noted. For more detailed information on the terms used here, see the Numismatic Information Directory at Chuck D'Ambra Coins.
