<P> Bundling money together with a simple elastic or paper device is as old as paper currency itself . However, measured and standardized straps are a relatively new idea . For example, until the mid-1970s, The US Federal Reserve counted bills by hand . That is, they employed 55 currency counters whose job it was to count as well as, by touch and feel, authenticate bills . However, as the amount of currency in circulation increased, they found that they needed a more efficient way to count currency . To help the Currency Counting staff keep up, the Bank began strap - sorting the $1 to $20 notes . Straps were visually inspected and weighed against a counterweight equal to the paper mass of 100 genuine U.S. notes . </P> <Table> <Tr> <Th_colspan="2"> Strap Color </Th> <Th> Bill Denomination </Th> <Th> Bill Count </Th> <Th> Bill Total Amount </Th> </Tr> <Tr> <Td> </Td> <Td> Black </Td> <Td> $1 </Td> <Td> 25 </Td> <Td> $25 </Td> </Tr> <Tr> <Td> </Td> <Td> Orange </Td> <Td> $1 </Td> <Td> 50 </Td> <Td> $50 </Td> </Tr> <Tr> <Td> </Td> <Td> Blue </Td> <Td> $1 </Td> <Td> 100 </Td> <Td> $100 </Td> </Tr> <Tr> <Td> </Td> <Td> Green </Td> <Td> $1 </Td> <Td> 200 </Td> <Td> $200 </Td> </Tr> <Tr> <Td> </Td> <Td> Pink </Td> <Td> $1 </Td> <Td> 250 </Td> <Td> $250 </Td> </Tr> <Tr> <Td> </Td> <Td> Green </Td> <Td> $2 </Td> <Td> 100 </Td> <Td> $200 </Td> </Tr> <Tr> <Td> </Td> <Td> Red </Td> <Td> $5 </Td> <Td> 100 </Td> <Td> $500 </Td> </Tr> <Tr> <Td> </Td> <Td> Yellow </Td> <Td> $10 </Td> <Td> 100 </Td> <Td> $1,000 </Td> </Tr> <Tr> <Td> </Td> <Td> Violet </Td> <Td> $20 </Td> <Td> 100 </Td> <Td> $2,000 </Td> </Tr> <Tr> <Td> </Td> <Td> Brown </Td> <Td> $50 </Td> <Td> 100 </Td> <Td> $5,000 </Td> </Tr> <Tr> <Td> </Td> <Td> Mustard </Td> <Td> $100 </Td> <Td> 100 </Td> <Td> $10,000 </Td> </Tr> </Table> <Tr> <Th_colspan="2"> Strap Color </Th> <Th> Bill Denomination </Th> <Th> Bill Count </Th> <Th> Bill Total Amount </Th> </Tr> <Tr> <Td> </Td> <Td> Black </Td> <Td> $1 </Td> <Td> 25 </Td> <Td> $25 </Td> </Tr>
