Possibly A '72 DDO?

Darn it! Well, only one thing to do. Look at more coins!

Thanks!

MD is flat and shelf-like, while a DD is sort of roundish. They look different by comparison.

I can't detect any doubling in the letters.

looks like a keeper to me.. its still a cool coin..

It is Machine Doubling and it is worth its weight in copper. Why would you want to sell a normal Lincoln on ebay to someone for way more than it is worth?

But you know what you have. One Normal Cent. I personally wouldn't sell it on ebay but that's just me.

I'm by no means saying you should or shouldn't sell it on ebay.

Ask yourself this question? Would you buy that for $5.00? Why or Why not

If you keep searching you will find Doubled Dies and other varieties. Happy Hunting!

This is from Errorvariety.com. Pretty much nails it on the head... http://www.errorvariety.com/OFD/MD.html

"Terminology:
Machine Doubling is sometimes called by a seller or a buyer as: Strike Doubling, Mechanical Doubling or Machine Doubling damage; the use of non-numismatic terms is also pevalant: sheer type doubling, ejection doubling, field doubling, shelf doubling, double date, and erroneously as a Double Strike or a Doubled Die. Others are clever and try combining the word double or DDO and juxtiposing it with other terms to make the coin sound more important.

ebay:
There is currently no place where doubling and its many forms are more confused, through ignorance and deception than ebay. The abundance of readily available information that accurately explains Varieties and Errors (in book form and free on the interent) is seemingly outmatched by the ignorant, misguided buyers and equally ignorant or dishonest sellers who peddle garbage. The auction titles and descriptions often contain inaccuracies or made up terms such as: double dies, double dyes, double date, double died, double die date, DDO strike variety, mechanical DDO type, doubled date obverse, etc. Many sellers are only able to describe what they see as "doubling" and generally know very little if anything about types of doubling or classes of Doubled Dies. Others are blatantly trying to deceive ignorant newbie collectors. Another range of auctions try and take the '55 poorman's double die (PMDD), a misnomer, and further apply that term to coins with MD on the ‘69S or ‘72P. In other instances the seller offers a coin as a possible Doubled Die or double die with a question mark (?) at the end of the auction title. In cases like this the sellers will offer vague descriptions, sometimes poor photos of coins with MD or DDD and make the promise of the buyer either getting potential high value coin for very little or some sort of glory as the discoverer if, you the buyer, submit the coin for authentication later. All hogwash designed to deceive buyers into buying a worthless coin."
