Error in the year 2007. And in front bumper of the train is missing some of the lines. Also, there is an error in one of the filled in train wheel. Thanks.
Die chips are very common on the UT SQ's. About 7 years ago, I searched several $100 Uncirculated bags I ordered from the Mint, and I found dozens of them with die chips in many different places on the engines. They're worth 25c each. Your coin appears to be well-circulated, so it's only worth 22c. Chris
