Variety & Error Coins

I would go with this

The SEM/EDX only can penetrate about .5 micrometers to 3 micrometers whereas a cent is about 1.5mm or 1500 micrometers, so plated, the device can only penetrate 1/500 the thickness of the coin. A normal minimal nickel plating is about 20micrometers, so a SEM/EDX can't penetrate through a plating of nickel to the inner part of the cent.

Hi. I have tried to post and insert the penny analysis. It wont work. Any ideas?
I get: It does not contain an extension, this is saved as a document. It wont upload. Help

 

This is the 1972 D penny that PCGS lab determined this cent to be 96 percent Nickel.

All I need is to be explained how to upload the document test results. Every time they say I need a .jpeg or .htm., I tried this to no avail.

Thanks Girldly

p.s. the scratches were made by my husband (in grade school). He wondered why his lunch money cent was this color. The mapping the company stated the entire composition is 96 percent Nickel (not coated)., PCGS LABS

These results are why I am desperate to insert them to show my friends at Coin Talk what I learned and paid for to learn. These tests were not cheap.

 

What format is the image in you wish to send?. You can go to the "support and feedback " forum, start a post . Find the document image on your computer , type "Testing photo insertion", then go to bottom of the post area and click " upload a file", It will then tell you what formats it accepts and max size and then click "Browse". "find the directory where the photo is located on your computer and then click on the file, and the process should start and the file will be loaded into your post. You can keep it small or full size. If this doesn't load it, people will notice it in that forum and help more. Hope this helps. Jim

 

That cent is absolutely, 100% plated with nickel. Also explains why the details are all flat.

There is no way this was made at the mint. Impossible.

 

Even if you can't post the results, can you post the test method that allowed them to determine the subsurface composition. Very interested to find out what type of Non-Destructive Method was used to determine bulk composition.

Thanks
