Here's somebody on eBay asking $1300 for a similar piece - evidently they're quite rare. I'd get this one authenticated.
I just bought it for $400 after reading up on the provided info. Not bad! It is returnable if counterfeit, though.
Possible to post better pictures? Look to have a coppery color with areas of silver gilding, though I believe this is just the lighting. Details look just fine.
It's the lighting. These are the typical seller's pics he takes. The "color" always looks similar on his silver coins.
I always get annoyed with how they grade these. I really believe this coin, as well as the other posted above, are substantially better than VG.
