This is a ridiculous and totally uniformed comment. Any coin, regardless of age, can be lost not long after it was minted and be in exceptional condition. I've dug almost 200 colonial silver coins, including about 85 cut pieces, and they've been recovered in conditions ranging from totally slick and almost unidentifiable to pristine with almost no wear at all (very similar to this one). I can post pics if needed, but Treasurehound's coin appears to be 100% legit. Please don't criticize other's finds when you really have no clue what you're talking about.
UPDATE: Here's a small sampling of some dug silver coins that exhibit little wear, and I can post many more like these examples. Click on the photo to enlarge.
