May I use your photo and credit line in FMTM-2 ?

Please contact Andy (andywoj00). Andy is the photographer. More images are available here.

For those not familiar with Class VII (me) - Die Varieties: Doubled Dies

Looks as if the denticles were cut too deeply. Each raised tooth is really a cut into the die. If the cut is too deep it could interfere with rim formation next to the collar. Suggests haste in doing the work....common enough in 1921 Morgans. Thank you. I have always been a bit fuzzy about the dent...

Would someone please explain/conjecture about what caused the rectangles at the base of the denticular clefts that are located below the date. Are these of the die, the collar, or maybe the optics? 1921-P VAM-32A I3R5 AW030720 Click on the photograph to view at high resolution. http://www.silverdye....

Great incremental work. Certainly a powerful addition to the Morgan database. Nice work with the tabular layouts for 7, 12, and 14. I wonder if there might be a home for some UHRLFCPs somewhere. Loren

Thank you for commenting. Interesting that the letter cited above might have been inspired by someone's signature work. Also, I did not know about using lime at the San Francisco mint. Perhaps this explains why the most photogenic, and affordable, Morgan dollars tend to be from the San Francisco Min...

Thanks Loren a#$&%$!

Oh no! I better get things in order.

(The work cold be done with an emery wheel or a horizontal lathe in the machine shop. I don't know which was in use at NO in that year. The irregularities imply a emery wheel was used - machinists would be sensitive to misalignment, etc.) Thank you so much for commenting. You might have noticed tha...

Do the coins share the same reverse die? For the most part; no. Here are more examples. Include VAM-12 in this library. The only shared reverses that I currently know about are VAM-22A and VAM-36A. Notice that the VAM-52A has both wing tips involved. 1883-O VNC-09 I2R4 LAE730480. Click on the photo...

Approximately 20 percent of the 1883-O varieties appear to have a "polished" right wing tip. For example, VAM-4 . Is this appearance due to polishing, strike, alignment, feed finger gouge, or something else? Thank you for commenting. 1883-O VNC-4 TF868724. Click on the photograph to view at full res...

Nice coin. If that is a cut wreath stem clash I see at the folded wheat leaf, it does not go with the wing clash at the jaw line. I would like to have a copy of that coin in hand. Nice.

In general, there is polishing of the lower hair and designer's initial for the second coin posted. But, the second coin appears to be an earlier minting than the coin of the original post. If I have the order of minting correct; state and stage are out of play. Thus, not only different coins; but a...

it looks like the date is doubled on the bottom of all 4 numbers. You might be observing what has been called stretch toning. During the life of the die, the date may "migrate" as the die wears (sinks). The properties of the metal on the rim side of the date may change in a way to alter toning in t...

Excellent. Thanks. In my limited knowledge of minting; I expected the planchet, if stuck in the collar, to strike the lower die rather than the lower die strike the planchet. I thought the lower die was stationary. Someone should write a book.

Click not once, but twice and wowser! The polishing lines. Great addition! Loren

@LorenAlbert Thanks and what is "giving up weight"? Funny, after I wrote that; I headed to Google and Duck Duck Go to assess just how esoteric "giving up weight" might be. We are in the midst of an obesity epidemic. Thus, weight loss dominates the search results. I have squandered much of my life i...

This might have been amenable to a poll. I am not used to the lighting trickery of scanners. The sharpness of the borders, it seems to me, preclude struck-through for grease. I doubt PMD because I see no evidence of roll up. I am betting on debris. But I am not giving up weight.
