The U.S. treasury recently announced that Harriet Tubman will replace Andrew Jackson on the $20 bill. As is usual with such changes, it was not universally popular.

TV anchor Greta Van Susteren suggested that we should leave Jackson on the $20 bill and instead create a new $25 bill featuring Tubman.

If Van Sustren's plan were adopted, the U.S. currency would have the following denominations: $1, $2, $5, $10, $20, $25, $50, and $100.

With this proposed set of denominations, would the greedy algorithm remain optimal for giving change (or would the U.S. public have to learn more advanced techniques)? Prove your answer correct.
