1753 Columnario Lima mint

Read GDJMSP's response to your earlier post about those particles.

Again, read GDJMSP's response to your earlier post, pointing out that the minimum acceptable weight of a genuine coin is 26.8646 grams.

Re weights , at the Columnarios .com website there is a reference to weights which states there was a 4% tolerance, I have reproduced here:

5. Weigh it. A real columnario (8R) will weigh very close to 27.0642 grams. Be careful with sea salvage specimens, however, as they tend to "loose weight" due to surface corrosion. The weight of the 4R is 13.5321 grams; 2R, 6.7660 grams; 1R 3.3830 grams; and the 1/2R, 1.6915. Note that the legal tolerance was about 4% for 8R.

4% of 27g. equals 1.08 gr. which would leave a coin such as mine at 26.2 gr. within acceptable weight .
It also has 38 'leaves' around the edge . ( still haven't managed to get it on a jeweller's scales yet tho )

It doesn't look porous under a watchmaker's loupe either.

 

Uncirculated columnario

Here is an uncirculated columnario with raised marks on the surface.

 

Do you have the link for this picture?

Thanks

RC, you have purchased a very advanced coin. I hope that it was purchased through an expert, as it sounds like you may be a bit of a novice to the series, and this type is highly counterfeited.

GDJMSPs points are spot on. The weight is a touch low, and his eye picked up some problem areas that I missed when I first looked at your images. In my opinion the weight is not highly troubling, but it is an indicator of a problem.

If this coin were purchased in any other way than from an known expert, I would not hesitate to send a coin like this into ANACS for authentication. I would go with ANACS as it is my understanding that Rick Ponterio is their contract expert for authentication. If it gets his ok, you're probably in good shape.

 

Hello Rick , thanks for the info, I don't live in the U.S , even so, is it possible to contact ANACS for an opinion. I purchased this from a seller who has 100% positive feedback as an e.bay seller for several years and has sold coins worth considerably more than my purchase so I trust her integrity.

I wonder about the products from the Lima mint as compared with the Mexico minted items, whether the standards were as high , for example the artwork on some of the South American coins such as Guatemala are nowhere near as good , I have a lot of these old coins and theres no two the same!Even the diameters vary considerably and they're certainly not all fakes.

 

Well, the variations should be very small, particularly with this type. They were issued under surprisingly advanced specifications. If you have several coins of this type with a remarkable size difference (more than 1 mm standard deviation) I would have them checked out without a second thought.

I mean, I want to agree with you when you say that they are certainly not all fakes, but it's not impossible. Ebay has a staggeringly bad ratio.

 

Here is a link to the uncirculated columnario, it is e.bay no. 260040644541

 

IMHO that coin is as uncirculated as the '03 cent I got in pocket change yesterday.

 

More images of my 1753 Lima

Hello
I have posted some further images, these are photos from different angles as the first were scans and the coin can look quite different under different lighting conditions.

 

You know I like the looks of it, I really do, but it still should be authenticated. Here is one which I acquired that is spot-on weight wise but still fake as it will attract a magnet

Regards
Ben

 

Bone, all I can say is: ouch.

 

Oh, It wasn't that bad. I got a refund thru paypal and the seller didn't seem to want the coin back...

It's probably a modern counterfeit, but you might want to contact a guy by the name of swamperbob. He has staggering knowledge in the origin of columnario counterfeits - you never know, it might come with an interesting background.

 

1760 fake

I remember reading about those 1760 fakes , apparently copied from an original with a flaw in the die which all the copies featured ! It doesn't even look very convincing .

 

Trust me the seller (Sunshin*str*asur*ch*st) was a photoshop pro. THey had sold the same coin three times I learned and had refunded the cash three times. I filed a mail fraud case and they didn't seem to want the coin back...
