I am looking to purchase your old beer and soda cans. I can make an offer based on the description sent to me and pay cash within an hour after commitment. There is no need to see the cans first.
To get the best price, include every possible detail and photos if available. Also include the history of how you obtained the can.
I have been in this hobby for 40 years and know about cans!
I also pay finders fees for information that leads to the purchase of older cans.
