If we want Ronald Reagans face on U.S. currency, we should reinstate the $500 dollar banknote and put him on that; or maybe even the $1000 dollar banknote.
Good idea. IMO, Presidents should be reserved for paper currency and other figures should be on coins. I would change the paper denomination to look like this:
$1 = Washington
$2 = Jefferson
$5 = Lincoln
$10 = Teddy Roosevelt
$20 = Jackson
$50 = Eisenhower?
$100 = REAGAN
$500 = McKinley
$1000 = Cleveland
