"Until they can get the weight of those dollar coins down to where they are comparable to dollar bills, they won't be replaceable."
That was a common "pre-adoption complaint" about the equivalent coins in Britain and Canada.
In actual practice, it was quickly determined to be an absolute non-issue.
The reality is that few people (unless they're primed for the strip club) carry around enough dollar bills that substituting the same amount of dollar coins is an issue.
So yeah, I don't buy it as a valid issue. It's more of a conceptual issue than an actual issue.
Well, I could see it being an issue for people who like to walk around with a bunch of $1 bills wrapped in a $50 or $100 bill to make it look like they've got a phatty wad, but that's just street posturing. I'm sure Bogie's seen *expletive deleted*it like that given where he lives/works.
Oh, just to add more to this discussion, the Euro zone never issued a 1 Euro bill. They skipped that and went right for the 1 Euro coin.
The Euro is fractionalized in cents. Oddly enough, the Euro zone mints 1, 2, 5, 10, 20 and 50 Euro cent coins.
I'm pretty sure that the US hasn't minted a 2 cent coin since the 1870s. The US 20 cent coin was a resounding failure and was only minted for 3 years in the 1870s.
