Post by: Giantgg on September 29, 2013, 05:47:24 AM
Hi,
Would like to seek help from forumer here How to identify a old proof coin which is in circulated condition?. By using higher magnification to see the surface is it alright to identify old proof coin.

Thanks in advance

IMHO!

Unfortunately, no one provided any info on the subject so far. The question is not related to Chinese coins and/or any other particular country. Occasionally Proof coins are found in circulation or severely mishandled. But even in circulated grades it is possible to identify them. However, only coins of up to Proof-45 may be identified by looking at their surfaces and strike. Coins below this grade do not have any luster left or enough detail to make the identification possible and can be identified as Proof only if it is a Proof only issue or Proof dies are distinguishable from MS dies. So theoretically grades as Proof-4 or Proof-20 do exist though being highly uncommon. So summarizing, coins above Proof-45 may be identified the same way as all other Proofs, and coins below that grade are not possible to identify unless they are Proof only coins or made with distinctive dies. Then the question arises how to identify any Proof coin at all. All you have to remember, Proof is a special technology that made a coin and it is not a degree of quality or degree of how mirrorlike are the surfaces. So look for that technology, Proofs are made with their own dies and sometimes it is possible to identify and distinguish them from dies intended to make business strikes. Find quality photos of Proof coins similar to your coin and try to compare dies. If any original surfaces left look at the mirrors, strike, relief... and of course experience counts.   

Best regards,
