Amputating: I'm new to coin collecting, does every single coin have a variety?
Not every coin date/mint mark has varieties but most do. However most varieties aren't worth any premium nor do they solicit much interest, It's the outstanding ones that seem to get the bulk of interest, look to the popular series; Like Lincoln Cents - 1922 plain D, 1955 and 1972 Double Die, my favorite series, the 2¢ pieces have the 1864 Small Motto and the 1867 Double Die. Morgan dollars
have had a big push with varieties due to the popularity of VAMs specifically the Top 100 VAMs, Buffalo nickels
have there share too, the 1913 Type I & II, 1916 Doubled Die, the 3 legged and D/S mint marks, Mercury dimes
have the 1942/1 and the micro S, just to list a few of the more popular one.
I suggest that you acquire the Cherry Pickers Guides (now in the 5th edition) co-authored by Bill Fivaz and JT Stanton, there are two volumes, the first one covering the lower denominations is a good place to start on lower cost coins. Also if you like Morgan dollars
then get the TOP 100 VAM
keys as well.
You can and will make money if you learn what to look for and attend coin shows or dealer shops, using knowledge gleaned from that book. In the past decade I've turned quite a few under $20.00 coin purchases into $200.00 or more, and a couple of times a lot more (twice over $1000.00)! Certain varieties are a lot of fun to search out, and when you finally find one for the price of a non variety coin - you SCORE big time if you decide to sell, as varieties generally have a strong market for the tough and popular ones.
