I have an 1892 and 1893 Columbian Expo Half Dollar. Both show strong signs of doubling on the reverse. The only varieties that I find on NGC Variety plus are double dates and over stamped dates. Please help me.
Are these varieties defined? Please share any info you have. Do I have something special? Thank you.

To my eye this appears to be Machine Doubling, also known as Strike Doubling. The 'flat and shelf-like' appearance of the additional material is a key indicator.

There is generally no price premium for machine doubled coins.

I have to agree with nickelsearcher, but
the doubling does make this coin a bit more interesting, and worth noting on a 2x2, and more saleable versus a similar coin without doubling.

Probably want to get it into a new 2x2 or at least get rid of that rusty staple.

Help me understand Machine Doubling.

Is Machine Doubling going to be a one off? For example, I have 2 1893 Columbian Halves with the same Machine Doubling. Does that make it a variety?

Are doubled varieties listed on NGC Variety Plus NOT Machine Doubling? Isn't a DDR or DDO just Machine Doubling?

Thanks

Here's good article on the NGC site that explains things well. (Note: it uses the term "Mechanical Doubling" vs. "Machine Doubling" but the two terms describe the same thing.)

Multiple coins with the same diagnostics can be struck with machine doubling.

No. The linked article explains the difference.

Thank you Commems!! Upon reading the article all I could think of is DUH!!. It very clearly defines the difference. However still seems difficult to identify the difference.

It can definitely be tricky. You will find that it gets easier after seeing more examples of each type of doubling.
