Hello everyone! I got this pillar 8 Reales from recently and weighs 26.98 grams. Need to know if this are Authentic or Fake coins. I had compared many pictures from online and I think its real, but still not 100% sure with it's accuracy. Any comments would be appreciated. Thanks!!      |

It does have correct weight and design characteristics but I see a few areas of concern. You should search for other posts here about measuring specific gravity and XRF scans. If genuine, a 1758 8 reales in AU condition would have a value of several hundred USD. If you paid much less than that then it's a good indication that it's a modern forgery.

jgenn thanks for response :) Where do you think the suspicious of this pillar reales? The overlaps on the rim in two sides are clearly. It's there any concerns you think it's forgery? Yes you are right it costs hundred of dollars. I brought from a high reputation ebay seller, I don't think it should be a modern forgery.

Some things I see that are suspicious: the edge has a section that is not centered, two circles on the top M of the assayers initials, some surface issue between I and S in HISPAN, Line through the R in VTRAQUE, surface issue between Q and U in VTRAQUE, surface issue at bottom right of right pillar. Surfaces issues in protected areas indicate they are not likely to be post minting damage but an unusual problem with the die. Also I can see a nice reflection of your fingers -- proof like surfaces are not typical. None of my comments are conclusive one way or the other so please check to make sure the coin is 90% silver and if you can get a good XRF scan it should show a small percentage of gold as part of the alloy. However, in general it looks good enough that it might get into a TPG slab. Edited by jgenn

K35889k35889 Scientific tests are the best way of authenticating this series because the majority of the coins being sold today are not genuine.
Modern methods of die copying make the details of the design of almost no value in determining if the coin is genuine.
In this case, I agree with jgenn that there are some features which I see that are troubling. The edge is one of those features. I can see one overlap but not both. The design that I see is not quite correct but it is so badly damaged that it is hard to tell.
Since the weight is correct, the next step is to prove it is actually silver. Density testing is the best since it considers the total weight of the metal and it can not be fooled by a surface coating of silver.
If the density is correct 10.31 then I would do an XRF tests to confirm the gold content of the silver.

Really appreciate for jgenn and swamperbob response :)) I think I will do the scientific tests for sure to prove the actual silver contain inside. Here is few attached higher quality images from that seller, I hope it can provide more details compared to the images I posted few days ago. jgenn The line through the R, and few minor lines on surface issue between Q and U & I and S could be the minting issue? And few lines on the top left side between the crown and "plus" pillar are the same problem as well? I will post more overlaps pictures later today.   Edited by K35889k35889

K35889k35889 The edge photos are great and I can see that the laps are positioned correctly at 180 degrees apart, however the segment lengths do not seem to be identical in each lap.
The shape of the segments are not good in my opinion. It appears that the edge dies were losing their grip on the metal near the overlap, resulting in a very shallow impression. That can happen, I have seen it many times and attribute it to a worn edger.
I do NOT like the pictures showing the "dot". That to me looks like a casting seam. It gives me serious concern that this coin is a numismatic forgery. Where did it come from?

The oval dots looks bit suspicious to me, not really sure how it appears on the lap. Just like swamperbob explanation, it might possibility be a casting seam. It's there any pictures or examples of genuine pillar 8 reales two sides' overlap? I brought from an Australia based ebay dealer "Sterling & Currency". |
