CAUTION - X-RATED - How to determine a coins thickness in a slab.

in U.S. Coin Forum
I couldn't figure it out until recently. Then, it dawned on me - take an X-ray. So, I took 4 coins to work today and did just that. The 2 coins on the right are the controls with known thickness, the ones on the left the unknowns. All are PCGS.

They seem to be intermediate between the knowns and unequal to each other.

It got me curious enough that I'm going to crack them out and weigh them.

I'll show you the CT scans later....image

    I've heard that X-rays turn red copper black within a month or two. image

    Two questions:

    1. What payer are you going to bill for this diagnostic work-up?
    2. Will you publsih your findings in AJR?

    My icon is the result of an Xray experiment. I wanted to see if I could distinguish a date on a Morgan with Xray to see if you could figure out the date on an unopened GSA. Didn't work, but I got a nice pic of a buffalo nickel.

    I didn't use the USPS anthrax dose. image

    None of the coins are red anyway.

    Will that CT be with contrast? image

    Will bill to PCGS for leaving the weight off the first time. image

    No - not needed. image Actually, it was non-diagnostic because of beam-hardening artifact. But, it's fun to see the innerds of the slab and the peripheral sealing. I was thinking of doing a MRI but thought better of it. image

    If that coin gets cancer, it's your fault.

    What is with the X-ray? What ever happened to an MRI? OK with the CAT SCAN also. Now what happens if this gets mixed up with someones medical records. I can see it now. Operation due to coins inside the patient. Patient being sent to PCGS for final analysis.

    Carl - if we take an xray and there are no coins, we read it as "No change". image

    Zues - want a second opinion?? Your ugly, too. image

    I've been told I tolerate fools poorly...that may explain things if I have a problem with you. Current ebay items - Nothing at the moment

    I'm going to have to try that sometime, in the name of image quality testing. There's a neuroradiologist in Manhattan that tapes dimes to the patient's left cheek (on their face) to ensure there's no laterality confusion when viewing images. You could see some design elements of the dime in the x-ray. I'd think with the right dose and a detector with a resolution of about 0.150 mm/pixel, you could make out the date on a well struck uncirculated Morgan dollar much better than you can with many pictures on eBay.

    Holy crap, I never noticed you icon was a buffalo nickel until now!! image

    The problem lies with the lack of contrast when trying to xray a Morgan the difference in thickness between the date and field isn't enough to show well. and also, it's a big chunk of metal and you have a hard time getting any xrays through it. That's why I tried the buffalo, they have a nice high relief and aren't quite as thick as a dollar. I got some decent half dime pics, but not enough detail to see the date.

    Are your images showing you the thickness of the coins, or just the thickness at the rims?

    I always thought that it was a 'scope of a cervix. Well, there you go.
