You can collect 8 reales cobs that are not damaged by exposure to seawater. These are, of course, easier to assess for possible authenticity since the weight would not be diminished by corrosion and the coin design should be better defined. With shipwreck dreck you have only the reputation of the issuer of the COA to trust.
Consider this -- how would someone else be able to authenticate this coin if you lost the COA?
