Another "Nice, Problem free coin" on eBay to avoid
The seller apparently overlooked the fact that the coin had been used as a pin or button and then was re-engraved to cover up the soldering. It's one of the better re-engravings I've seen but it's far from "problem-free". I notified the seller (but not eBay) and will wait for his response. I'm not sure if eBay will pull auctions for misrepresenting a coin this way.
