Big Month on coins

Well,I made the it to rank #140 this month.Well,no one gets the free roosevelt ms67ft dime.Now I have a new challenge.I will send someone 10.00 for guessing correctly of the coin I am going to buy in may.Rules are: 1 guess per member.Send me you guess.First one to get it correctly wins.Look at all the coins I collect,and and what grades I like.My only HINT is that the auction ends in may and the coin I want is being sold at heritage auction.you need to send me the year,mintmark,exact grade and company it is certified by.NGC or PCGS.....This month (April) I will be slowing down in buying because,I am buying a coin in may.Here is a list of coins I bought in march...
