He most likely got them from circulation. He started collecting after working at a bank for while in the late 40's. Along with the complete book of LWCs up to 1947 were a lot of shoeboxes filled with envelopes of sorted cents up to the late 50's. Unfortunately many of them were damaged over time due to poor storage (can see examples in my other posts). I've been working through it for the past year trying to see what's left.
