    My assumption is that this is a 1751 Cob 8 Reales - Potosi Mint.

    26.7 Grams

    30MM x 34MM

    Is it authentic? I have never owned one or even held one in my hand. To my inexperienced eye, it compares favorably to pictures of genuine pieces. If genuine, how is it graded and valued? Thank you in advance for any input.

    Looks real, but its definitely not 1751, likely 1500s-1600s, but I don't know much about Spanish colonial silver.

    The weight is near correct...from your image it looks good to my eye. However I cannot tell you 100% positive. Nice looking cob...I buy it if the price was right.

    Dan Sedwick in Florida would be the man to contact. A real gentleman that is generous with his time and knowledge.

    I believe you are correct, 751 appears on both sides.

    Check Sedwick's auction archives for similar cobs to get a sense of valuation.

    Apparently I was wrong, the Spanish did mint crude cob silver up until the 1773. I always assumed cobs were phased out way earlier on.

    In almost all other colonial mints they were, but in Potosi they were not.

    Looks real to me.

    Yes, I see 751, along with a P, which would make it a Potosi 8 Reales 1751.

    26.7g is within the range one would expect for a cob (noting that they are often shaved etc).

    As others have mentioned, Sedwick is the authority on this.

    Given it will be fully attributable, I'd guess it would be worth around $200 or perhaps a bit more if you're patient.

    P.S - actually, I'm probably a bit conservative in my estimate above. You should be able to fetch $250 to $300

    I have found 2 Reales while metal detecting. A 1718 2 Reale and a 1775 1 Reale. 24146520-C2B9-4149-A174-196EF9A88CD7.jpeg 24146520-C2B9-4149-A174-196EF9A88CD7.jpeg 88315367-4708-4C95-9138-E6A3803446E7.jpeg 3A9B2F54-9824-4E8A-A82E-77E1AC572A3A.jpeg B988CFF7-1003-47AE-A16F-4A066AC1B35B.jpeg

    Nice @Chip Kirkpatrick

    Where (in general, I don't need to know your secrets) did you find them? I'm currently conducting some amateur research on the circulation of coins in colonial america. Any found coins are therefore of high interest.
