Looks like a large date with MD=machine doubling. No added value.

@dee, first welcome to CCF. Second, you have a nice example of Machine Doubling on this cent, but unfortunately that doesn't add any value so only worth one cent.

Classic Machine Doubling. I have one almost identical to this one. Worthless, but I sometimes keep worthless coins if they are interesting.

One telltale for Machine Doubling is the shelf-like look. Another is that the Machine Doubling often shows up on the date AND the mintmark. Where true doubled dies may only show on the date, for example. Lastly, if it looks like someone smashed the edges of the date down, then the actual tops of the numbers (devices) look narrower. In true doubled dies, the centers actually look wider. Look at the "1". If you ignore the flattening, the number looks narrower.

Nice example of MD though

A lot of the 1968-1972 had Machine Doubling often. Even the 1969-S "Big DDO', many of these had Machine Doubling on them:

Note the date is hub doubled, but the yellow arrows are showing Machine Doubling. So you can have Machine Doubling on a doubled die, and on normal coins, because it is caused by the machine. Only a doubled die can produce a double die coin. The die that created your coin was normal, thus it is not a doubled die, but has Machine Doubling. A doubled die can have Machine Doubling, but a [i]true collector[/i\ prefers to buy a coin without the Machine Doubling as it is a distraction to a doubled die. Like on your coin, note the affected areas are reduced in height, not raised. Again note on the doubled die, the date will show a raised extra hub device area on the die. But note, the mintmark is normal on the DDO. The die creation process happens first. The mintmark punch is later added to the working dies. So when you see the date and the mintmark affected the same, then it is Machine Doubling. So your coin was from a normal die, not a doubled die. The Machine Doubling altered the coin, post strike. Hope this helps.
