There are several levels of effort that go into slabbing a coin. Unfortunately, the level that is involved in typing the text that goes onto the label is not the same as the level that assigns the grade.

I suppose this one also counts as a MTT, albeit a kronenthaler minted in Brussles

Atocha 8 Reales Silver?

Be wary of anyone trying to sell you a coin from any shipwreck without a legitimate COA. As mentioned, Atocha and some others carry a "perceived" premium so you can see the incentive to claim its from a particular shipwreck. Also, silver replicas for jewelry were made so just testing for silver is not sufficient to authenticate that the cob may be genuine.

Is This Atocha Shipwreck Coin Authentic?

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?

The NGC census shows 7 straight-graded in equal or better grade. Can you find any auction results for the straight-graded ones? HA has only sold 3 "details" graded ones.

There is no standard to apply to "details" grades. The XF is clearly superior and may be very attractive to collectors (very likely outside of the USA) that don't care about TPG grading.

25.68 grams? Is that a typo? No way that could be regal.

Could also be a bullion forgery. Someone put a big X on the neck -- that's NOT a vote of confidence for regal weight or SG.

The correct approach is find examples of regal issues and then study the differences between them and your example. The big auction sites have many examples of these for you to view.

Lol, as noted in the previous post!

This is clearly a fake. The details of the design are not regal.

There is an obvious problem with the host coin so any other issues are secondary.

1/2 Real Spanish Coin Die

Hard to say if it is a genuine die as these were never released from the mints without significant defacing to prevent counterfeiting. The few photos of dies that I've seen have all been round. There were no hubs at this time -- all dies were unique having each element struck from individual punches.

The market for such items is really small so it's really hard to place a value on it. You should show it to experts to determine if it might be genuine. However, a contemporary counterfeit die would still have value to certain collectors.

The die sinking on the reverse is much less precise than seen on issues from just a few year earlier. I see some die doubling on the lower lion that may account for the different appearance of the tail. The low weight on this coin without circulation wear is suspicious as it is below tolerance and should have been caught in assay.

However, I see many punch characteristics that match Potosi issues of this period. You should have no problem getting it authenticated by one of the TPGs (although, the effort they put into authentication is suspect).

Here are my three examples from this period:
