So, what do you think the purpose was to compose such a letter?

I cannot answer your questions because I have never seen the actual FIRST $100 ISSUE that was actually on the game... and what I am reading suggests there was more than one event involving those $100 chips.

Could it be the HAND PAINTED edge spot order was enough to make them different than the original $100 chips and everyone (Paulson. casino and NJ gaming) was happy...?
