Dating service started in 1964
Schlitz started using them in 1963 and other brewers quickly followed. Most brewers got rid of these by 1942, but a few continued to use them after the war.
By 1967 few brewers still used flat top cans that had to be opened with a church key. Only three brewers that used opening instructions on their cans after 1950; Genesee, Sterling, and Falls City. Aluminum cans came into wide use in the 1970s but the first ones were being sold by Primo and Coors in 1958-1959. A few other brewers including National, Hamms, and Budweiser started using them in the early to mid 1960s. Flat top 15 and 16 oz cans came into use starting in 1953 so a flat top 16 oz can would date between 1953-1964.
A lot of states also required a tax stamp on the can, which usually appeared on the lid if it is a flat top, on the cap if it is a cone top, and on the bottom for a pull tab.
Unfortunately I do not have the data needed to date a can by its state tax stamp. Sometime when a brewery closed another brewery would purchase its brand names and the new owner continued to use the old brewery name.
American Can Company Cans: The American Can Company (Can Co) put a very tiny date code on their cans from 1935-1953. The exceptions are some cans made for states like Oregon that banned the pull tab due to litter in the late 1970s, and some cans were made as flat tops to sell to collectors in the late 1970s and early 1980s.
If you can has the "Keglined" logo on it and if it's from that period, you might be able to read the date code. The earliest pull tab (an Iron City) was sold in 1962. Then it dates from the mid 1970s until the early 1980s. Does it have opening instructions on the side of the can showing how to use a church key?
Yes on paper dating sounds very liberating and open - but what is the cost?
The left and right swiping generation now struggle to form meaningful relationships because of how superficial life has become. Good men and women wanting long term relationships - i.e. Here at Go we are about marriage only - not dating.
Before that date brewers had to include a tax statement.
Our users are matched with our Practical marriage questionnaire for compatibility - and instead of dates, they go on Marriage Meetings.
There are often exceptions to these rules so I'll try to include them when I can.
You'll find Schlitz cans with copyright dates of 1946, 1949, 1954, 1957, 1958, 1960, 19 and dates afterwards.
Look along the seam for the year on most Schlitz cans.
