*probably reproduction per user findings* Hey All. Found a coin I could not pass up this weekend. 1705-1723 Mexico City minted 8 reals with the assayer mark of J For what I can see of the bottom 3rd # is its 1710-1719. Unfortunately, the last digit is lost to history. Have not weighed it yet, but have had a dealer look at it and they were impressed.   Edited by CGCoins

From the site and it looks like it. Take it back if it was sold as authentic.   |

Sure looks like it guys, good eye! I did look all over the edge for anything that stated copy or did not look like it should be there, but did not find a thing. However it matches that piece too close to feel positive about.
Luckily, it was not expensive, and may just go as a cool silver piece in my pile.

If it's fake, how can you be sure it's silver?

nfine - already tested as silver at the baseline of 92.5% silver and it passed. Plus if it came from the St. Augustine mint as it appears it did, they are .999 Silver.

It's still quite nice as a replica. It's very difficult to obtain a legitimate example of this series (KM# 47) with strong details. If you ever wanted an excuse to drill a hole into a coin, it'd make for a nice jewelry piece even.

It is very rare? for cobs to be struck from perfectly even thickness piece of metal, to yield and even strike both sides.
From what I understand, the silver plate was hammered (not rolled), and cobs cut from it.
I must admit, I need more education on this subject.
I am by no means an expert on these, but it does raise doubt in my mind.

For most Spanish 8R cobs, part of a bar of silver would be would be cut to the proper weight (~27g) before then being hammered. Due to the irregularity in the shape of the cut silver it was indeed very uncommon for the entirety of the planchet to receive such a uniform and sharp strike, also why one can find many with cracks, soft strikes towards one side, ridiculous shapes, and other irregularities. If the coin was overweight after being hammered, only then would a portion would be cut off. The late klippe style cobs from Mexico (1732-33) were generally overweight to begin with, and made in a screw press, before then being cut off which is why so many of them are square-shaped. Of course, the St. Augustine Mint reproductions take more care in the process of producing each individual coin; but back in colonial times they were crudely done, the dies weren't the best either.
I'm not an expert with these either, just fascinated with them.

A pretty worthless newly made copy if you ask me.
