Aluminum metal lot of 21 rolled coin trays bank STOKES

This is a nice old vintage lot of rolled coin trays that were removed from an old bank that was torn down. They appear to be aluminum and are stamped: The Stokes System, Quality Products Co., Charlotte, NC.
The lot includes:
(10) $5 pennies
(5) $20 nickels
(1) $50 dimes
(5) $100 quarters
They are in great shape, but could use some cleaning.
Please ask any questions that you may have.
