I am looking at a 1993 ASE and noticed a couple of patterned die gouges that I can not figure out. Looking at the obverse there are 4 pointed die gouges that are seen on both sides of the coin on a horizontal level. One set at approx 8K, the other at 4K. the die markings show 3 large pointed gouges together with a fourth located a little lower and a little smaller on both sides of the coin.
Are these feeder finger gouges? Not sure what could cause these marks on both sides of the coin.
Can anyone explain this to me ? Just really curious.
Pardon my poor images, but I hope you can see what I am referring to. My explanation might be better than my images.

Some coins are just plain "Interesting"

No feeder fingers on the Proof presses. There is a rotating disc with reeded holes in it that bring planchets between the two dies, stops, acts as the collar during the strikes, and then carries the struck coin out during the next rotation.
The marks on the die do look like they start on one side, continue through an imaginary arc across the design, and resume at the other side. My first thought is that the rotating disc got out of sync so that the planchets and the holes in the collar disc were off center when the dies cycled. Thus the upper die could have impacted the edge of the off-center collar, causing the marks.
Nothing on the reverse die? Perhaps they pulled both dies and repolished them and they did not go back in together.
I reserve the right to think about this more.

Your pics are fine.
Not sure why the other poster can't see them

Hey TD
Nothing at all on the reverse. The marking/gouges are the same on both sides of the ASE on the obverse only.
It is interesting and very noticeable with the silver in hand. You are correct in that if you drew a horizontal line across the obverse, both sides are equal and level.
Silverpop - the marks emanate from the rims and both point toward the bottom of the planchet at the same angle.

--- If it should happen I die and leave this world and you want to remember me. Please only remember my opening Sig Line.I think he is correct (as he usually is) that it is a problem with
the reeding collar being out of alignment. It seems each of these marks
coincide with a reed point.
This was the year proofs were begun at Phil. & not at S.F. and their
equipment may not have been ready for it.
Rocco, are you able to see the reeding from the rev. side & if so, are there
any signs of the reeding being off center?
Looking through a number of ASE's for '93 & surrounding years, in CoinFacts,
there are a few examples that have odd strike patterns on the rims.
Just my two cents!

Hey LML,
I just had a chance to look her over carefully. The marks do coincide with the reed points, but the reeding looks to be normal overall.
Looking closely at the reverse, there are no signs whatsoever of this or any other anomaly.
One observation to note:
If you drew a line from these "gouge lines" from both sides, they both point directly to the dead center, K6, on the coin.
They must be used for some sort of alignment purpose...or so one could conclude.
