Looks like the plating moved during striking. It is on the devices above the head also.

[fiddle-fart]

so I guess would not call it a tdo (triple die obverse)

Usually the profile isn't affected with a DDO. The outside devices show the doubled hubbings. There are a few strong DDO's that show a doubling on the eye (1955D-1DO-001) Beard (1955P-1DO-001 & 1984P-1DO-001) Where the ear & and/or beard is affected. But most of the time it is not seen as doubled on the designs.

There are probably other examples, but these are the most known that I can think of.

Yep, looks like that coin has the plating shifted, not a DDO.

One of the nicest DDOs that shows doubling on the top and bottom of the bust is 1984 1DO-002. It's a DDO most people ignore but it's one of the nicest and the more you look at them the more you notice. I like it better than the well known 1984 doubled ear.

Notice how the doubling shows in the top hair and lower bust:

now not to be hard headed about this, but something I've read
from Mike Diamond talked about "stutter strikes".
Although this is on his want list

It has stutter strikes......
what is a stutter strike?

any info will be helpful

Thanks
Mike

It simply looks like disturbed plating, possibly related to the blistering seen elsewhere on the coin. The blistering develops at the moment of the strike and it's conceivable that blistering can hug the margin of the design.

A "stutter strike" is entirely different. A stutter strike features a weak incomplete image next to the normal image. It's produced when the hammer die (it's always the hammer die) makes light, transient contact with the planchet's surface before it completes its downstroke in a slightly different position. A stutter strike is something of a wastebasket category as it can occur in association with several different types of errors. It never occurs on an otherwise normal-looking coin. It's always associated with some other error, like an indent, partial brockage, off-center strike against a stiff collar etc. Stutter strikes are quite rare.
