If that is really a 61 (which feels insultingly low) that is the best 61 I have ever seen. There are 63s out there that are worse than this coin.
The grading landscape has changed drastically over the last 18 months or so, and old habits are dying hard. I've been seeing some pretty strict - in cases, overly-so - grades in new slabs from all three, and we've discussed them at various points including this one. On the other hand, we're also seeing some pretty egregious errors, too.
Whoa ! that's way too tough . I didn't expect anything that low at all , unless the pics are hiding the hits and I doubt they are hiding any that would make it a 61 .
Tighter grading is no problem. But don't make up criticism of too-loose grading by erring in the other direction, as I think it was with this coin.
Are you sure that it isn't an AU-58 that got a pretty bump? That's the only justifiable reason that I can see for a 61.
Whenever I see a WTH grade on a ms61 or 62 gold coin that is what I think. In this case I am not so sure. Looks pretty unc to me.
