You can make your own COA, and I know a beach hunter who does for his finds. The salvor who recovers the treasure usally makes a COA, to verify the find. The COA by nature is a descriptive document that states the facts about the find. When it was found and how, and usally a brief description of the shipwreck and history of the piece in question. It will list the salvage company and its signed by owner or officials that are part of the operation. In the case of a beach hunter it's the same, only there is no official company....just the salvage is listed. Template forms can be found, and some really fancy certificates can be made. Now also remember this......a COA , is also a great document for the IRS to find a paper trail when it come to enforcing tax collection.....no receipts but you sold the coin with a COA stating all the details, and documenting a transaction, so could probably be used in a tax case against the salvor as a record of transaction.
It is all very shady if you ask me, and I know salvors at this very moment that use blank COAs that have been pre signed by salvors. I was just recently offered a blank COA that was signed by Jack haskins. I was told we would fill out all the details and leave the date of recovery blank !! I won't name names, but I was shocked......it would be totally false, and would give credit for my coins recovery to jack haskins !! I love jack, may he rest in piece, and to see a stack of blank COAs with his signature on them was very disheartening. He absolutely had to know what he was doing at the time....and its just disappointing. Then I realized the COA can be really important, or just B.S. on a fancy piece of paper. Why in the hell would I want to give credit to someone else for finding my treasure.....I will make my own COAs, and state that I was the salvor, and my finds were made in a legal fashion under no contract with the state, and found between the low tide mark, and the heal of the dune.....in my case there was no dune....just the road bed of US-1. I will have mine notarized also
So what I've found out in this very confusing topic is that COAs vary widely, and can be super official looking, but are often false in origin, and sometimes not factual concerning the veracity of the find. Some are very well respected, and others can be a complete lie. When I asked about why I would do that....the answer was simple.....if you want to sell 1733 treasure, then a jack haskins COA virtually assures you will get the best price, and everyone knows his name.....no one knows you yet !!🤥🤥🤥
