What person, event, or idea should be commemorated on a coin? Why?

Rapidly approaching is this nation’s 250th, and so far, I have seen nothing that indicates a significant effort to issue affordable, well-designed circulating coinage or paper money honoring this achievement. Recycled designs by the U.S. Mint are not worthy. High-priced “collector” issues aren’t either.

I don’t recall that we have ever had a coin commemorating The Manhattan Project. This project was essential to bringing WWII to a conclusion and saving countless lives had a prolonged invasion of Japan been necessary.

Many thousands of people worked tirelessly for years in secrecy, without recognition, to bring the project to success.

I think Q. David Bowers should be on a commemorative coin because of his outstanding contributions to the field of numismatics.

In general, any event, person, or idea that has positively contributed to the country/society commemorating it/them.
