OK that's right, I forgot the 20th anniversary sets. I don't know how since I bought 20 sets of them when they were on sale (there was a 10 set limit per customer but I used my aunts address and stuff for the other 10) I was thinking about how many US Mint Annual Uncirculated Dollar coin sets I have and they started in 2007 and was thinking they made these with the first year of issue and forgot all about the 20th anniversary sets for some reason. Thanks for reminding me
