I USPC did not have any organized records during thes production dates.

All documented and archived here by me.

When they needed info on a chip/production, they had to look through every single book which took hours. All documented and archived here.

Whe the president of the) Panama Numismatic Assocl met with me in person to explain their (USPC) problem, I mailed them a complete index of every photo so they would at least know if they made a certain chip and then know what to look for.

The index of all Howdy's photos (way before the book) was made up by Eisenstadt's housekeeper/neighbor.
