Great. I will be waiting for an update.
But as NGC evaluates such coins, it does not look like the usual round metal money. These Spanish 8 reals are not round at all. How do they know the year and the mint?

That's a lot of cobs. They look cleaned, which is probably why they note "excavation". They don't look corroded like seawater cobs.
The date is very clear on the 1739, and shows as "739".

Harlan Berk had a little boxful of 4R's at one time, but it was only 2-3 dozen.

Are they all from Potosi and are they all from a single hoard that someone uncovered?

This group is part of the Sinclair hoard, and they have been stabilized after being in saltwater. The XRF scans show 96.2 to 96.4% silver from the original 90% when they were hammered. Saltwater leaches or corrodes the copper out of silver, and based on the percentages it puts them at about 260 to 240 years or so in saltwater.
As far as corrosion you have to keep in mind how deep the pieces were and how deep they were in the sand and other stuff on the ocean floor. The deeper coins are in the muck the less damage they take.
We own them all and the 1st group should ship out tomorrow. The date ranges are 1737 to 1753 with every mint and even a few errors. Grade range looks like about 70% or so will be UNC's. So, this group looks to be one of the finest groups recovered.

Maybe the 1754 8Rs came out of Colombia. Funny about the muck. We made a human planer, if yo'all don't fish, a planer is a fishing implement that drags a lure deeper into the water (unusually a fly). So we made a planer out of plywood and bricks and dragged, dredged my buddy off of Steinhatchee and found nothing. Young and stupid. No one died.

The first group of 50 is now in shipping, but we will not see the grades until the package has a shipping label created. We should have all 300+ back in hand by the end of October.

Recently I've been after the last Potosi cobs. They are extremely crude past 1760, and those from the 1770's are hard to find.

Here is the 1st group of Grades of a 50-piece submission.
6 Cob's grade AU and 44 graded UNC for a total of 50 coins. One more group of 50 is in QC and should ship out tomorrow or Wednesday, NGC doesn't post grades until they are shipped.
