Hello All, this is my first time to load the images of a coin for discussion. Weight of this coin 26.88 grams and diameter 42mm, recently bought from an ebay seller. It does not look like fake but I want to ask is there any coin of this type be so large in diameter (42mm). Most of my Spanish/Mexican or Spanish/Bolivian coins range from 39-40 mm. Can the diameter a factor to determine it is fake or not? Can any one give me an idea? I am sorry that I can't post the Observe of this coin after I have been trying a number of times.

 Try renaming picture when you up load  Also picture of edge would be very helpful for identification. Sometimes cost is a factor may I ask how much it sold for on Ebuy  |

ebay # 200766647716... The larger diameter is the norm on the late 1780's-early 1790's Potosi 8R. The piece is genuine, and the price you paid is right around where this should sell for (it probably could even have sold for a few dollars more, though not too much).

wonghinghi Hello, I saw that coin when it was offered and I had placed a $55 snipe bid on it which was not high enough to win. Based on my review of the picture posted I had classified in as a Transfer die forgery - probably made in the mid 1800's.
Now I may of course be incorrect, but look closely at the dentils to the left of the Portrait. They make solid contact with the letters and appear to be recut as if added to a mold.
A few of the letters are doubled which could be a transfer error. The surfaces are grainy especially in the fine dentils of the hair. I was hoping to see the edge to see if I was right.
I believe it is a Class 2 forgery of the silver type made for use in China.

Bob -
See the tilting H in HISPAN and the high 1 in the date - if this makes a difference? After viewing several hundred for the book a non-symmetrical HISPAN is usually indicative of a contemporary if not Zacatecas. Could be just the photo but I am seeing a copper oxide hue in the photos - suggesting? an off-metal issue with high copper.

Hi John - I agree with you that the tilt of the letter/numbers are more typical of contemporary forgeries, but the edge detail for me seals the case that the coin is not an original but was likely a Class 2 counterfeit made for the China market in England or Shanghai.
The edge has the partial diagonal cuts and the circles are squared off a bit. The crude application virtually assures the coin is NOT REAL.
Regarding the color - I had chalked it up to lighting but a high copper alloy is possible. It would be a good one to test with XRF to see what comes as a result.
So wonghinghi if you ever want to get rid of it I would cover your costs of $73 to get a closer look at it.

I don't like counterfeit coin and I have no intention of collecting contemporary counterfeits. No problem.I can sell it to you by $73 and if you pay $76, I will ship it by registered mail to you, swamperbob.

You should mask your mail a bit though, so robots don't put it in their spamming list.

Guys, while that of course can be a usual attribute seen on contemp. forgeries, don't go nuts diagnosing the crooked lettering and date digits. Some goofy die designs for the portraits (spacing, alignment, etc.) came out of the Potosi mint as compared to the Mexico mint. Compare this piece from an upcoming auction... The date alignment is slightly less extreme, but it's fairly close. Also, I pasted the seller's full-size pic for reference. Looking at that questionable rim area by CAROLUS... there is some apparent die clashing within the lettering. For sake of argument, could that be what's affecting the denticles in that area?   |
