More old dumpsite bottles found

[angifogg]

I am assuming this is an old Coors bottle, most of the paint on the bottle is chipped away. The bottom of the bottle is stamped with 8517 5 58 11
Does the 5 58 mark the date that it was bottled?

Any thoughts about this bottle would be appreciated

Thanks

Looking at the label remains, I would say 1958 would be about right. ffd
