1966 Roosevelt Silver Dime

Ok gotcha, you need more pics of the edge. Also another poster mentioned I should weigh it. Ill post again.

Hi,

I can almost guarantee that in any major city one can easily find a coin shop or jewelry store that would analyze this potentially exceptional error coin using an x-ray fluorescence analyzer.

I personally had a rewarding experience involving a x-ray fluorescence analyzer last month.

Thinking that the local shop would not analyze my four suspect Alaskan gold nuggets for free using their x-ray fluorescence device, I also brought in about $ 40 worth of worn silver quarters to exchange for cash.

Upon my request the shop then happily pulled out their XRF x-ray fluorescence analyzer gun and determined that my four gold nuggets had a total aggregate amount of

8.42 grams of 21.4 karat AU (gold)

In summary since each nugget had a distinct gold weight and AU karat anatomy the shop gave me a free report for each nugget separately as well as a combined aggregate compositional report. All of the tests combined took them all of two to three minutes to complete.

I know that it seems to be overkill using this expensive machine but what if the '66 error dime in question contains neither of the expected compositions of:

a) for 1965 and subsequent years:

Metal Composition: 91.67% copper, 8.33% nickel
Total Weight: 2.268 grams

nor

b) for 1964 and previous years:

Metal Composition: 90% silver, 10% copper
Total Weight: 2.5 grams

If this 1966 dime turns out to contain neither of the above compositions, you could be the proud owner of an 'error of an error coin'(now that's a really BIG MISTAKE) and the sky could be the limit for what someone might pay out to own this coin!

Calculating specific gravity and weight only, for example, will never accurately portray the precise elemental makeup of this dime should it turn out not to be categorized within a) or b) previously described.

IMO

PS:

For the scientifically-minded viewers interested in drilling down in greater detail deeper into this subject I attached an excerpt,



from an 18 page paper entitled,

'Study and Comparison of Coins by X-ray Diffraction (XRD);
Preliminary Findings' by Andrew Bearnot and Ashley Greene

dedicated to analyzing various coins using x-ray fluorescence technology. This study addresses both XRF and XRD technologies.

This is why I always search 1965 stuff that would be the mountain top of cherry picking for me!! A silver POST 64 haha be a conversation piece for the ages. And while this train of thought is active...what if a 90% 65 kennedy surfaced?

Unholyroller yes indeed I have seen articles on post 70 40% ers . I will definitly start searching for something on post 64 90% (except proof of course) great info always looking for new cool stuff
