Large Lot of 300 Vintage Stock and Bond Certificates 1850's-1970's Railroad Oil+

Description

Offered at no reserve auction is this lot of about 300 original stock and bond certificates.
There are actually about 350, but about 50 of those are duplicates of blank certificates from the Boston/Albany Railroad seen in the sixth photo here and I'm not including those in the total count.
They are in varying degrees of condition, most show cancel stamps, punch / staple holes, etc...
This is an as-found, estate fresh lot that has absolutely not been picked over by me.
Many blue chip American companies, past and present, are represented here including GM, TWA, Pan-Am, etc...
They are largely railroad, energy/mining, and transportation firms represented here.
The oldest date I see is 1859 on a Providence-Boston Railway certificate (with a few Ohio railroad stocks from the 1860's as well) and the latest I see is about the mid-1970's.
I've tried to picture everything here but am absolutely open to questions or providing more images of anything else you'd like to see.
