  1. Cathrine, I don't know what you paid for the coin but I'd be inclined to keep it. These coins very rarely survive in pristine condition unless they've been protected from day one and your own coin photos show exactly how most of these early proofs appear in hand. I just wish I had the knowledge to photograph my coins in the way that PCGS did - my collection would look absolutely stunning !

    I forgot to add that we weighed the coin before submission to PCGS (11.16 grams).

    How much relevance can we give to a quoted weight of a coin ? I have a cheap Chinese electronic scales which gives a very different reading to a coin that I bought with a quoted weight. I cannot believe that these scales are particularly accurate, especially when they give readings to 2 decimal places of grams. Freeman weighed most of his coins I believe but using what technology ? And if coins weigh differently on every cheap scales, is there any point to weighing them ?

    This is the Spink coin. At the time of the auction it was heavily covered in PVC plastic residue from improper storage in a PVC plastic holder. PVC residue must be removed to avoid damage to the coin from hydrochloric acid released by decaying PVC and we did so. This is a standard and non-invasive procedure. 

    James, are you happy to describe how you do this ? I have one or two coins that would benefit from such treatment.

    Cheers, Richard
