Bought this recently from an ebay dealer with good stats based on it being a centered strike, but upon receiving it alarm bells immediately started ringing. Weight is 26.99 but ring tone is off, the details look too darn crisp for a coin this age, the color is too nickel-blue if you know what I mean, and edge is seriously manky - looks like it's been heavily filed. But the clincher - if I needed one - is that it is medal rotation, not coin rotation. I've never heard of these being done that way, so I'm fairly confident that this is as fake as a #3 bill - unless someone can advise otherwise...   |

I don't know. Here is the numista page on your coin. It does mention coin rotation, the weight is basically right  |

Based upon the weight, let's just assume for a moment that the silver purity is right (which eliminates a contemporary counterfeit), so determining its specific gravity won't help. If it's then a modern forgery made of more or less the correct amount of silver, analysis via XRF (xray fluorescence) might pick up trace elements that shouldn't be present in an earlier 19th century alloy. Or it might pick up trace gold, which'd tend to authenticate it. I'm not overly concerned with the "too darn crisp" aspect. I see subtle details that actually seem to match up well with another advertised and presumably genuine (albeit uncertified) specimen. So if it's indeed a phony, it'd seem exceedingly well executed on several accounts. See: https://www.bing.com/images/search?...=1280&ch=647Colligo ergo sum

There are very well struck coins of this type having sharp details and yours could be one of them.

Is there anywhere authoritative I can find out more about
possible medal-orientation strikes?

For what it's worth I did check books I have and did find some good info on that coin but I did not find medal alignment specifically mentioned.

My 1836 and 1855 8 Soles are both in coin alignment.
Doing a S.G. is somewhat tedious so you can just slide the coin down from a N52 neodymium magnets, it would be distinctly slow if the silver content is good.

Here is a Bolivian 8 Soles 1842 that is also medal alignment. It weighs 26.9 grams, is not attracted to a magnet, and has crude edge reeding that looks filed down in a few spots. There are probably others out there   |

Thanks for the replies, guys. So there ARE medal
alignment coins out there. Mine is definitely
non-magnetic, so this is all very interesting. Maybe
I was too pessimistic...

Thought I'd add a few hastily-taken edge shots to show what I mean:    |
