I do not see anything to suggest this as a Doubled die. No split serifs or wide spreads. I see die deteration and or strike doubling (Aka machine doubling) But for help with your question a full picture of the obverse and year/mm goes along wayl. What year is this? Looks like a early 1982-1984?
We need better pics to answer your question. From what little I can see it appears to be machine doubling.

Would you like to take a shot at posting a definition for "split serifs", where your coin would fit that definition?
That's a serious question. Your pictures show nothing even close to split serifs. I can't even come up with a guess at where you might be going wrong, to give you a pointer in the right direction. It's like if someone posted a picture of a tiger and asked if it was a lion. Well, yes, they're both cats. Beyond that... really not. You posted pictures that show a coin. Beyond that... really not.

But I could be wrong. The year and mm is needed!
yes it is an 82 no mm aren't these split serifs ?

The key to MD is flat shelf-like doubling.
I just cant tell what is flat md or not....so this inflate md?

Look to see if surrounding letters or details "slide" in the same direction.
Sometimes on things like nickels they'll do this naturally and sometimes they'll get a type of circular, rotated doubling 1945-70ish.
There is a ton of mechanical doubling out there.
Anyone else beginning to wish there was no such thing as a DD?
This may help.

Think of walking up a flight of stairs at the Lincoln Memorial in DC. That's what Mechanical Doubling looks like.
A split serif looks like this:
A Double Die means exactly that. Two dies overlapping each other. But it's on the die not caused by striking or minting a coin.
I have to commend @SeanB for tirelessly searching for DDs.

In a word: No.

Ya maybe we can see triple D's now that would be nice...

Don't give them any ideas or we will.
Machine doubling...not a doubled die... Cheers, RickO
