1970-S LMC Floating Roof And What May Be 2 Rim To Rim Die Cracks

Very nice coin!

Good eye.


I'm curious about the Lincoln statue on the reverse. Looks like a pin head with giant knees.

Interesting analysis, Jovian - thank you!

The mark between the columns Is part of a normal design on the 7th bay.

But there is also another issue with that area. While removing a clash on that area, the fields were reduced and with that field area removed (the bay) it leaves a raised area on that area of the design. So now it show the extended area you are seeing on the 7th through 11th bays. These are not extra columns, just altered fields on the die. (the bays on a Memorial dies are the outside edge of the die. thus any polishing on this area will affect the bays that were polished to remove a clash line)

Sometimes this die abrasion can reduce the size of the devices.

Hope this helps Pete.

Interesting set of die cracks. Don't recall seeing before.

1969 and 1970 LMC dies seem to be the two most common years that die abrasion produced the floating roof. I still wonder why or what changed during that time period?

Must of been clashing and polishing some dies left and right is all I can think of. One day maybe I'll start cataloging the dies, but not today. Thanks, Doug.
