1987-D Lincoln Cent - Possible D/D DDO

I am always still learning and somewhat new to these DDO and RPM type coins.

So I put a side by side photo of my mint mark (on the left) to the URL on coppercoins.com suggested by John1.

Does not my mint mark look very similar to the example here on coppercoins?

What would my coin be classified as then if it is not this coin?

I am still confused which is normal for me.

Thanks

It is difficult to say for sure from the photo but it looks like the plating is split along the front of the D making it look like a doubling or RPM.

What I see is on the left side of the vertical bar..is it just me ?

A D/D is an RPM - not a DDO. A doubled die ( DDO or DDR) happens when the die is created using a hub and a lot of pressure. A repunched mintmark (RPM) happens when the mintmark is added to the finished die by hand, and the punch slips or is hit a second time out of perfect alignment with the first punching. Their causes and results are very different from one another - not a good idea to use the terms interchangeably.
