Weight and bulk

Us here in the UK have managed fine with a thick and "heavy" £1 coin
for 22 years with no complaints. Billy

Exactly. There's absolutely nothing wrong with the current US dollar
coin. It's only nominally more weighty than quarters, and no one
complains about them.

It always cracks me up -- the exact same people complain that dollar
coins get confused with quarters, and that they're too big and heavy.
You can't have it both ways.
