The Federal Reserve bank creates a large amount of shredded currency each month. These bills are pulled from circulation because of damage, defacing, or age and instantly shredded.
We take it.
We make cool stuff out of it.
The material on which bills are printed is actually a custom blend of 75% cotton and 25% linen, created by Crane Paper Company exclusively for the U.S. Treasury. This special mixture is known as "rag." It's much more resilient than paper and can't legally be used by anyone outside the U.S. Bureau of Engraving and Printing.
The U.S. Bureau of Engraving and Printing churns out about 38 million currency bills of varying denominations daily, worth in total about $750 million. Printing plants located in Fort Worth, Texas and Washington D.C. use 18 tons of ink per day just to keep up.
OK. Here's where the math gets fun!!!!
A dollar bill of any denomination weighs 1 gram.
There are 454 grams per pound.
Billium uses about 2.5 pounds of shredded currency per square foot.
If all the bills were 1's - there would be over $1,000 per square foot!
If all of the bills were 20's - there would be the equivalent of over $20,000 per square foot!
If all the bills were 100's - there would be over $100,000 per square foot!!
See - math is cool!
