Countermark on Spanish silver

Obviously I know what it is. An 180? Spanish 2 Real with most of J. Warren's countermark across the obverse.
This was dug a couple weeks ago at a quiet colonial cellar hole in northern CT.

I just don't know who J. Warren is. Guessing a merchant somewhat local to the area. But after poking around on the interwebs, all I've figured out is my answer lies (hopefully) in one of Gregory Brunk's books, which are long out of print and worth their weight in gold apparently.

Anyone happen to have a copy of the American/Canadian or the Merchant books that could help ID who J. Warren was? Thanks!

Have you considered looking at the census data? I would guess J for James. Good luck, I hope you solve the mystery!

That is a great looking coin! Hope you find out some info on who J Warren was.

Nice to hear from you again! You hunting with Donnie and Dan at all? That's a SWEET find! Have you tried J. Warre? That was a British surname...or maybe you can clearly see the N... Just spit balling. Congrats!!!:clapping:

That would be a no , Drew

It's 100% Warren, Drew. I know Brunk's book lists multiple Warrens, including J. Warren. Plus you can see a hint of the "N" on the edge of the coin.
Thanks for looking, and some ideas. I may have to find a genealogy whiz with this one. It worked earlier this year for a wedding band I dug 5 or 6 years ago.
