beer has ingredients similar to bread and mold will form on it like it does on old bread. As for the various colors i think that is caused by bacteria fromthe human mouth and also what the person was eating..
Old beer cans can be collected. There are many collectors who would pay a decent price for a rare old beer can that can no longer be found. Beer cans can also be used to craft things by creative people. Things such as couches, suits of armor, model airplanes, and several other usable items have been made out of old beer cans.
Cans
A "slab" or "case" of beer is usually 24 bottles or cans. In some places, cans come in 18 or 30 packs; these are not usually referred to as "slabs."
The answer is, liquid nitrogen ISN'T used in beer cans. Nitrogen GAS is. And the reason nitrogen gas is used in beer cans is to emulate draft beer such as one would get out of a keg(as opposed to cask) beer.
There are still many beer can collectors, and beer can collecting clubs. They aim to find perfect, very old beer cans. Some advertise online looking to purchase those collectible cans. As far as "collecting" beer cans on the roadsides, it is still done. The price per pound for recyclable aluminum varies frequently. Most who collect for extra income find it hard work for little money.
some beer cans are larger than others
It takes 32 12oz soda cans, or 28 beer cans. Beer cans are heavier. (BUT !! Beer cans can be brought back to any liquor store for a refund same as beer bottles... What makes this a much better deal is that if you bring 28 Beer cans to a metal scrap yard, you will get about 1.00$ for ther scrap aluminum, but bringing them back to a Beer store you will get 0.10$ every can, if you add this up it equals 2.80$ therfor you make about 2.8 times more money...)

Yes it does.
Many of the MASH beer cans are valued in price close to $20 each. The exact price of the can will depend upon its condition.
