Below we show how to narrow down the age of beer cans, by (A) surveying the big picture-more obvious considerations, (B) reviewing relevant publications, (C) delving into the can manufacturer's logos and codes, and, finally, (D) walking through an example.First check out the obvious features and characteristics of the beer can: A statement like "Internal Revenue Tax Paid" was required to appear on beer cans from June 01, 1935 through March 30, 1950.Early flat tops often displayed a "Cool Before Serving" line on the front of the can or "Keglined" on the front of the can.For an explanation of the types of beer cans below, see "Types of Beer Cans."

To further narrow down the date of American Can Co.cans, we can interpret the Manufacturer's Printing Code. produced cans with a small code on the back of the beer can, indicating not only the manufacturer but also the physical plant location and the date/year in which the can sheet was printed.This code is called a Manufacturer's Printing Code (or "MPC" for short).For many American Can Company cans, the text of "AM.Cans were made (mostly) of steel from 1935 through about 1980.With many exceptions, steel cans generally date between 19 and aluminum cans date after 1980.
