Question about shipwreck coins and 'orgin'
I was looking at some Spanish 8 Reale shipwreck coins, and on some COA's or label inserts it has 'orgin'. I saw one orgin as LT 12, others were 3 or 4 digit numbers. Does that refer to the orgin of the coin as far as where in the wreck it was found? I'm sure they do some sort of grid or mapping of the wreck before and during recovery. Maybe the orgin letters/numbers are tied to a specific location on the wreck in which it was found?
