Found 5 of these in a roll.

Are these doubled dies, or machine doubling?

 

[Mr.eX]

Machine. For it to be be doubled it literally will overlap like the 55 and 72.

 

[manoverboard70]

Worth keeping?

 

[moff347]

They are in great condition and are a cool find. Why not make a 5 cent investment

 

[omga747]

Tough to tell from the pics, but even if it is machine doubling, they look pretty cool and are definitely worth the 5 cents to keep.

Machine doubling and/or die erosion doubling, the dies look like they were pretty beat.
