It may just be my own opinion - haven't exactly examined "hundreds" of them - but old ANACS UDM's seem to me to be the absolute pinnacle of reflectivity and they were rather tougher than anyone else on mirrored coins back then.
Dave, correct me if I'm wrong, but I thought I read somewhere that ANACS uses a minimum of 8" reflectivity for UDM, whereas, NGC (?) and/or PCGS (?) use 12". Is that an older standard, or is that a current measure? Chris
Since you won't take my word for anything, I'll just post a link to the Anacs website. http://www.anacs.com/(A(NGB9bZZdzAEkAAAAYmI3MTg3ODQtMzdlMC00YTE5LTg1NDgtMDUyNjgyYWQwNThiglxR5jTqqD6DKVzy4ZO4S6_nfo01)S(zo2emc550o52jf45epnqj5ik))/contentPages/ShowArticle.aspx?ID=8 Anacs UDM need 12" mirrors Here's a link to PCGS, if you click on "more" next to DMPL, it will say at least 6" mirrors http://www.pcgs.com/grades/ Once again, your information is incorrect.
I wasn't talking to the village idiot. I was asking for information from someone who knows more. Chris
Now you're getting downright mean. You are the one who is incorrect, and that's why I posted links from the actual TPGs to prove your ignorance. You can call me names all you want, you are just proving my point.
I get lost on this topic with ANACS. I believe their standards have changed back and forth over the years. I can't keep track of what they used and when.
Speaking the truth isn't being mean. Go cry to mommy if you don't like it. You still don't get it! Chris
You're the one who doesn't get it! You are wrong. You're not speaking any truth. And saying "go cry to mommy if you don't like it" shows that you are also immature.
Yes it's on their web site today but what was it in the past? They have a history of changing standards. As I said, I can't keep up with the standards they have used and when.
You're still wrong! Incorrect! Mistaken! It must get you all riled up to have the village idiot prove you wrong. What does that make you?
There is another exception along with authenticity of the coin and that is when the label authenticates a meaningful provenance.
Man, did you guys stay up all night arguing? Do me a favor and stop bouncing it from thread 2 thread, I can't keep up
The article on the website was from 2007. In 1991, when they introduced UDM coins, the standard was 12". I think it's fair to say their UDM standard has always been 12" until 2007, but I would hazard a guess and say it still is 12".
