A 1-gallon milk jug can hold approximately 4,000 aluminum tabs pulled from soda cans, and 1 million tabs is worth about $360, as of October 2014. Thus, a jug of 4,000 tabs is worth about $1.44.
There have been many circulating rumors about the value of pull tabs from soda cans, but most are false. For example, there have been rumors that a milk jug full of tabs fetches as much as $100 or even $500. Another rumor involves the exchange of tabs for kidney dialysis, which also is not true. In reality, tabs are worth no more than their weight in recycling exchange.
