Have you updated your want list lately? Good idea. There are always a few coins on that list that are dream coins. Mercury dime collectors want the 1916-D. Lincoln cent specialists want the 1909-S VDB. Type collectors want the small eagle coins. Some want list may never be filled.
Try a new kind of want list. Pick a coin or two that interests you, one that you may not have a realistic change of owning. Learn more about the coin. Check articles online or in your favorite coin publication.
Entire books have been written on the 1804 dollar, the 1913 Liberty nickel, and the 1933 double eagle. Check out reference books that cover the coin you like. So many specialty books are available, perhaps to buy or to check out of the ANA Library. And there are always auction catalogs to check. Some of those catalogs are reference books in themselves.
Whether it's the Chain cent, a 1895 Morgan dollar, or another special rarity, make a list of coins you like and want to learn more about. You'll learn something, and that will make you a better numismatist.
