1808 British India 20 Cash- Admiral Gardner Shipwreck

Thanks! We got it for $90, which I feel is a great deal. NGC has MS60 at $300 and Proof at $650 for this series... where do you think this one would grade?

I have a certificate of authenticity that this is from the Admiral Gardner, but who knows. The dealer could very well have slipped me another coin's certificate.

The ten and twenty cash in MS grades and above, could have never come from the shipwreck; they should all show at least some evidence of saltwater corrosion if they did.

Actual genuine coins from the wreck are surprisingly more common than I originally expected. Shipwreck coins seem to be available for all, if you wait patiently enough for a pair to become available. I have a uncirculated pair with slight but obvious corrosion. I paid $20 for the pair about 15 years ago.

I would imagine that a proof pair would be extremely rare, and would be correspondingly valuable. THEY would never have been aboard the wreck of the Admiral Gardiner.

I understand why a TPG would not wish to grade a coin with corrosion, caused by whatever means.

The uncirculated 10 and 20 cash coins pictured also have slight but obvious signs of saltwater corrosion; they are well above the average than the more commonly seen examples from the wreck.
