A quick look-up on the internet suggests those units date back to circa 1938. Shipman Manufacturing Co. was one of the major players in stamp vending machines in that day and there were a number of different models with counter and floor standing pedestals, along with different finishes, etc.
Here's an auction site showing what appears to be the same item as yours, partially restored, with new lock. etc., which sold at auction for $65:
Obviously, your examples were later adapted to accept Quarters rather than Nickels in the first slot. Likewise, the above image shows that the knobs were originally made of Bakelite, which are obviously missing from your examples.
While it doesn't seem these machines have a significant value, they are certainly nice nostalgic pieces that many collectors would have interest in.
