Ah, so they are all non-circulating according to the link - a collector's only offering. That makes more sense. The mint must make plenty of money on these commemorative issues, because the dollar coin has pretty much been an economic failure since the Ikes. Too bad one of innovations won't be a circulating dollar coin that the public embraces.
Heck, all we gotta do is eliminate the paper dollar, but that's another story for the naked city.........
For Massachusetts, I'll throw out the name of Lewis Howard Latimer, but as for most other states, the selection process will of necessity be subject to the whims of SecTreas, the CFA, and political preferences.
In addition to Thomas Edison and the Wright Bros, Ohio can lay claim to the vacuum cleaner, automobile starter, traffic light, and teflon. However, in keeping with the spirit of another unnecessary, unwanted series of gold dollars that most citizens will never see, I would nominate William Semple and Amos Tyler who are credited with inventing (or at least patenting) chewing gum.
Louisiana shipbuilder Andrew Higgins. The Higgins boat used in the D-Day invasion. Also produced the first PT boats.
I think each state should immortalize someone that came up with something that is totally useless, so we can honor the dollar coin.
I'm guessing that where you live, there are no public transit systems that encourage its use, nor is there a vending machine major player who uses the dollar coins. Just a wild guess. Realize, however, that both things do exist. Where I live, small-sized dollars DO circulate, and even half dollars do where I recently moved from to get to my current location. When I left the ANA show in 2016 to head from Anaheim to Burbank, I already had my Amtrak tickets, but the local trains there use ticket vending machines that both accept dollar coins, and give them in change. This is no backwater; we're talking the LA corridor. CT'ers can write all they want about what people don't want, but places are different, and many CT'ers seem blissfully unaware of that. There ARE other reasons than serving CRH'ers for banks to handle coins, you know.
