And the number of posts that have said they have one? And the number that insisted they did and we were trying to rob them?

Oh, and the number that said they would post the graded coins in our face?
and the number that never did ?

But there were a few who returned to say they learned something.

 

An electronic microscope won't help.

 

You, uh, just happened to pick up an electron microscope to look at coins, huh?

Seriously, Tommy; as said earlier, just look at your coin and compare to a known example. Actually, here... this should make it a LOT easier for you.






The first is a quick crop of one of your photos, while the second shows the same area from the PCGS photo(s) posted earlier in this thread. Rather cut and dry, isn't it?

 

Yes thank you

 

Of course, but remember this is a rather extreme example. With minor doubled dies, markers can be a godsend.

 

Don't want to confuse the issue that Fred and Books brought up , as I agree with it.

BUT, if you actually ever get the use of a SCANNING Electron microscope, Coin varieties would be one big area of my use. I took several classes in SEMs in the 70s when they were relatively new and I was use to using the TEM ( which has higher resolution, but basically useless on surface structures. Back then they were barely available inthe lab. Today most universities have SEM labs, especially for study of surface antigens on cells and viruses and microorganisms. They are "almost" as easy to use as light microscopes, but very high resolution and being digitally integrated can magnify from 10X -60,000X or higher with great depth of field than light microscopes. They can stack images and if tilting the stage produce 3-D images of huge size. Expense of course limits wide usage in coins and such, but if someone buys me one, I will take a few years off the forum and play.... Not a B/S/T offer

OK will this work

 

This work ?

 

Not sure what you are implying @Tommy Barrios. Is that what an electron microscope looks like?

 

Yes

Yes

 

Here is a well known reference for you.

If you still think you have A DDO_001.
Then and only then should you proceed with the microscope,
Hopefully when you see the flat machine like doubling, you will understand!

I am sure that I have a full roll of common coins, just like yours!
buried in an ammo can.

On a side note how much did that little gadget cost you?

 

Tommy, that looks like a disassembled USB microscope, so no it isn't electron. Many use them ( unfortunately) as their resolution is not up to that of a similar optical scope, but what ever might help. I would much rather use a nice hand lens or a "dissecting scope" with camer attachment.

 

This was taken with the PRO scope 1960 ddo1 ?
