If you are asking whether a coin graded PF58 has been circulated, the answer is: Probably. The grade indicates that the coin has some apparent wear, and a proof can be worn just as a business strike can, if someone has foolishly spent it (or Daddy's collection has been raided for spending money ). On the other hand, it might just be a weak strike that somehow got out despite the extra care supposedly taken with proofs.
Something that many collectors overlook. Proof is not a grade, it's a process. The 58 is the grade from the scale which ranges from 1 to 70. Proof 58 is defiantly indicates an impaired proof.
this ebay item This is the coin that I am talking about PF58, I am very interested in it. Can someone tell me is the price fair? or too much.. And also the seller's comment about the coin, very interesting idea...=)
In this case I do not think it likely that the coin has wear. But it is obviously an impaired Proof - thus the grade. The reason for low grade (58 is low for a Proof as a rule of thumb) is likely due to improper handling and storage of the coin over the years. I have to say though - I do know some who are far more familiar with this series than I am who may quibble about the grade assigned. They would likely say the coin is over-graded. Of course that is a matter of opinion. Price wise - the asking price is about average according to the price lists. But if it were any kind of a bargain at all - that coin would be sold already. There are collectors who do nothing but search for these on a daily basis. So bottom line - the coin is probably over-priced. Just my opinion.
Just to amplify GDJMSP's comment, in general a coin graded at 63 is cataloged at substantially more than double what a 58 of the same coin would bring. This one is offered at more than half of the 2003 Red Book (not really the best price guide) value of $2,300 for a PR63. If I collected these, I wouldn't bid on this one.
