Two bits

I would like to know where " Two bits four bits six bits a dollar" came from?
Thanks so much.

Two bits is equal to 25 cents; they are counting in four equal parts of a dollar ending at a dollar, rather than ending on "eight bits".

the bits came from an old coin used in the collonies that was about $1 due to a shortage of coins they cut them into 8 parts (bits) the name 2 bits (one fourth a dollar) came to the quarter.
