The new Texas quarter has been out in circulation for a while now. Oklahomans, not to be outdone, have minted their own quarter. (The U.S. Mint is not too happy about it either.) The idea was a pretty good one except for one problem—the new quarter kept jamming soft drink machines. (We call them “pop machines” here in Oklahoma.) Apparently such coin-operated devices do not like the glue used to hold the two dimes and nickle together.
