Silverseeker, something to try would be buy 10 rolls of halves at the bank, go thru them keeping the ones you want, then carry a few of the ones you don't want to keep with you and when you have to spend $2.95 (just an example amount) at the convenience store, give them 6 halves. Do this until you have spent all the ones that you did not want to keep, and then get some more from the bank. Many stores you go to will have folks comment that they have people coming in time to time looking for them, so they do not have much of a problem getting rid of them. Just a suggestion. I have found almost 3000 40% halves this way and 460 90%, not to mention 200 other keepers (circulated proofs, 1974D double dies, errors, modern commemeratives, etc).
