What U.S. coins do you collect?

I have managed to collect a lot of Wheat Pennies. That is by far my largest collection with over 5,000 thus far. Other coins that I have collected would be Mercury Dimes (Full set)., Franklin Half Dollars (only need 5 more for a full set),

Of course I have at least one of each coin by denomination and series, however there are a few sets I do need more then others in. Some of those are the Large Cent, Liberty Walking Half, 1/2 Cent, etc.

If I had to name one series as my favorite, it would be the Mercury Dime Series. Right now anyway, lol.

So what do you collect?
