I'm not able to find references with regard to this coin which is for sale. I'm very tempted to take a chance buying it. Any ideas? Unfortunately these are the only pictures available.
Looks too good to be real. I say fake or cleaned.... How much? Weight and diameter are questions that you need to ask.
The coin was posted on a "Buy, Bid or Sell" webpage that is actually not used a lot. The site is used mainly for selling second hand items (almost garage sales). To mention .. i'm from Africa and if i buy this coin it will be the first 8 Reales that i buy. I'm an *ID10T* with regard to these coins. The price is currently less than USD 10
Sounds too cheap., even with the "counterstrike". I'd wait for more answers from "The Experts". Here is the Numista page.......8 Reales - Charles IV - Mexico – Numista
If it’s made of the “silver” the Chinese use in their Morgan “silver dollars”, you are paying $10 for pot metal.
I agree with Pickin and Grinin. If they are real counter punches there should be diminished areas around the punches where metal was pulled from.
Welp, first up, you've misidentified the coin. The host coin is actually a 1799 8 reales from Potosi, Bolivia. The counterstrike is from Minas Gervais, a state in Brazil. These were done in the early 1800s (some sources say 1808) Or it would be, if it were real (pun intended). If you search the heritage archives for Minas Gerais, most of these counterstrikes are quite crude. They nearly double the value of the host coin. I could be convinced that a genuine host coin (cleaned) had a fake counterstamp applied.... but I wouldn't touch this one without certification. A genuine piece would be worth $500 - $600 easily: https://coins.ha.com/itm/brazil/bra.../a/3013-27382.s?ic4=ListView-Thumbnail-071515
