Not fairly early, more like late 60's maybe even upto mid 70's. They made flat top soda cans into the mid 70's. Just my opinion, others may vary. Leon.
Repro, top is all wrong, I got the real thing, about 12 different ones & a rare amber one. All have the same top or similar & top nothing like yours. Leon.
most US Patent Coke Bottles seem to get anywhere from $1.00 to $5.00 in US unless some rare oddball variation. just my opinion. The older the better & usually the more value. Leon.
Mostly common stuff with little value. from that time frame 1950's & 60's mostly the ACL (painted labels) & Milks will have some value. Best to let those ACL's dry out for about a month before attempting to clean. fresh wet straight from the ground ACL's will most likely lose paint if to quickly...
