Let's play is it a PROOF or not...Trade Dollar edition
I've had this coin for a while now and I'm pretty sure it's a proof. This die pair is only known as a proof, and the reverses are always weekly struck. I'd also point out that you don't see too many circulation strike trade dollars that tone like this...but you do on the proofs.
Here's another example, same die pair, graded Proof 62.
There's a very specific pickup on this reverse die that helps with identification. The 2nd L in DOLLAR has a missing serif.
The coin has clearly seen a small amount of circulation...PCGS graded it AU55. The picture doesn't do it any justice, the colors are too washed out compared to the coin in hand. The mirrors are faint, but they are there. I owned the other coin pictured at one point and the mirrors weren't overly strong on that coin either.
Looking for opinions. Proof or not? If it's not, then we've found the first known circulation strike of this die pair, but it wouldn't be the first "first" in the trade dollar variety realm we've seen on this forum.
