Ok tonight, this is going to be a short one. I went through my used/mint postal card collection to find one that I feel would give the collectors a fun time hunting for it. Ready, here we go. Look under the Scott catalog for UX 87 (Battle of Cowpens), the First Day issue for this card was on Jan 17, 1981. The post card rate changed from 10 cent to 12 cents on March 22, 1981. Therefore, this card was only correctly used for about 2 months. So go out there and dig through those cover boxes for them. For those that wants to get a copy from dealers, it should cost around $10. Happy Hunting!
