Yeah, common enough date, detail looks correct at first glance... Something is definitely up with that rim area, however. That of course could be indicative of a fake... BUT I think it more likely that the piece is genuine and silver was shaved off. Look at how quickly the denticles taper off around 10 o'clock on the obverse, going counter-clockwise. Doesn't look normally-occurring... Relatedly, note how you have no denticles on one end of the coin... so you'd expect to see especially full-length denticles across the coin. However, even on that side, the denticles are "short". So, either the planchet is exceptionally small in diameter, or it was shaved.

The coin could be shaved, that would explain the weight but as far as the denticles is it just a quirk of the Potosi Mint? Here is a 1780/79 from my collection, weight 26.99gr, diameter of 39.65mm (on the large side for an 8), proper edge with overlaps at 180 degrees and the same short/non existent obverse denticles. In reviewing a scattering of Potosi dates from 1774 -1784 I have access to, many of the coins exhibit the same look.   |

Jfransch, your coin is much better than the one shown on ebay. Note the lion has "5" legs on that coin, the lilies are also much poorly struck. Your coin and the one on ebay were from different dies. I have the same one that I suppose it to be fake for years so had it been put in the junk box. To me, it is seriously underweighted (26.16 grams) and poor castles, lions and lilies strikings on reverse. The coin is shifted (is it a sign of counterfeiting), the squares and circles are small, there does not have two edge overlaps. I have catalogued it as a fake in my collection. Now I take it out for all of you interested to see if it has a chance to be genuine? Specifications: 26.16 grams, 39.2-39.3 mm, S.G. 10.37-10.38 (measured twice, equ. over 90% Ag)   Note the 5-legs lion.  Are the squares and circles smaller than the norm.           |

Jfransch, indeed, yours shows just about the same planchet size relative to the design... so can't base much on that. However, wonghinghi's piece is definitely another specimen (twin) of the same type as the one in the ebay auction - just look at that (almost identical) offset rim! The better, non-overexposed photos of this piece show everything wonghinghi just referred to... plus the relief level of the detail and shallow toning typical of a lot of Charles III MEXICO mint Chinese fakes I've seen. The whole rim/edge area and how the legend interacts with it is just strange (not legit) in general, and the circles/squares aren't correct for Potosi. So, yes... those are twins of a fake. |

Thank you realeswatcher for your confirmation so I am more sure it is a fake. But one more question, is there a chance be a contemporary fake? It does contain enough silver content.

Wonghinghi, thank you for the nice clear photos but I would keep that coin in the junk bin as an example of what the reverse of a Potosi 8 should not look like. I had never noticed the 5 leg lion before, thank you for pointing that out. I failed to focus in on the lions and castles on the ebay picture, as Realeswatcher pointed out, it is a die match for your coin and also a counterfeit. Edited by jfransch

I notice by the photos this 8R coin is in medal strike. I've got a similar Bolivian one dated 1799, which also is in medal strike.
Is this general for all or most 8R coins, throughout different mints and years?

My understanding is most Spanish Colonial 8 reales are struck with "medal axis".

We already have more than one coin on the page.
Talking about mine (first one), I checked and it is medal alignment.

So, would it be a yes or a no regarding the authenticity of first coin? Thanks!

The 1808 you had originally posted looked fine.
