Re: OT - Feed Finger Gouges Or ?

You're welcome. The physical situation of open vs close collar is more complicated, but the brief explanation of "fishtailing" will suffice for usual purposes. Increased die erosion farther from the center is a product of greater planchet metal movement, which in turn erodes the die. A primary steel...

Yes! That is a very good indicator of accuracy. Nice to see in numismatics.

Re: 1878-S dollar. Can you separate fact from fiction?

I understand about die states/"progressions" etc. I merely give that less reliability than some others do. RE: "Series 1 used collar #1 Reed count 186 for Vam 60, 26 EDS, 57 stage 1 and 2, Vam 26 LDS, Vam 57 stage 3, 4 and 5." Accordingly, the Ajax press was equipped with SF dollar collar #1, as wer...

Please explain how straight-line feeder/ejector mechanisms can produce radial makes on a die.

Thanks

Re: OT - Feed Finger Gouges Or ?

The "rays" seem to be radially oriented - not parallel as expected from some coin striking damage/

RE: "...the 1000 Vam 60s that were minted on April 17 or morning of April 18 were given away (j Gus Bert) or put into circulation." The VAM-60s were all made on the 17th ending when the reverse die cracked. We know these were delivered to the Cashier on the 18th along with 1,000+ from a different di...

Re: 1878-S dollar. Can you separate fact from fiction?

These three might help. The April coinage report has not been located. It should have been in E-229 among several boxes that contained only SF letters and documents. The May-June report is from one of those boxes and shows the quantities of good pieces struck from each numbered die. (Usually, such t...

Re: 1878-S dollar. Can you separate fact from fiction?

That is what I understood. Where did this come from: "We also know that the VAM 57 and 26 used the same reverse." This statement clearly says VAM 26 and 57 used the same ("identical')reverse....or is that supposed to refer the the REV HUB design not the specific die? BTW -- the following from the SF...

Re: 1878-S dollar. Can you separate fact from fiction?

The "Five standard dollars of this coinage" merely means Linderman wants 5 coins from those currently being made up to that date -- i.e., "Don't make anything special." This is a common request and is also used in relation to selecting Annual Assay coins and Special Assay pieces. There are multiple ...
