Do You Think Polymer US Bills Will Spell End Of $1 Bills?

I suspect Crane will license the technology from Note Printing Australia. They hold the patents on the process.
Absolutely the $1 and $2 will go away if we have a redesign on polymer, IMO. I am highly in favor of a new $500 note on polymer before the major redesign, but I don't think a $200 would happen. Two one hundreds can do the job just as easily. Very similar to the scenario of 1's, 2's and 5's. However, a new $500 on polymer would be a good test of the substrate, before it goes into high circulation notes, such as 5's, 10's and 20's.
No need to mint many more $1 coins, there are well over 1 billion of them in circulation or in FRB vaults. People would stop saving them and spend them when the $1 note is gone. The $2 note would be needed in quantity until the coin was developed and minted in sufficient quantity. Much like Canada from 1987-1996, except I hope there is no rush to get ours developed. I want to see a bimetallic $2 coin smaller than the $1 coin. That idea really works well in Australia.

Now hold on, Mr. Eagle. I have almost no problem with two $100 bills over one $200 bill, but when I start getting four $100 bills, I would rather have two $200 bills, just as, if the $1 and $2 bills are replaced with coins, I would rather carry two $2 coins over four $1 coins. I hate carrying four or even three $1 bills at a time if I could break the load down with more denominations, such as two $2 bills or a $1 bill and a $2 bill. And I hate it even more, having to carry up to four worthless pennies. I suggest that, if the government is going to continue to waste money on minting pennies, that they bring back the 2 cent coin, and try to force it into circulation. The U.S, Mint will NOT come out ahead with minting 2 cent coins, but they will be wasting less money on minting all of those stupid (one cent coins) pennies with 2 cent coins helping to meet the demand.

Also, I want our $2 coin to be the exact same specs as the Canadian toonie. Its only slightly larger than both our U.S. $1 coins and the Canadian loonie, and I would like our half reduced to a size between the nickel and quarter, as I have said a million times. Australia and the Euro Zone circulates their 50 cent coins, so, why can't we in the U.S. and the Canadians do the same?

But anyway, as I said, I would want to carry two bills over three or four, be it $400 in the form of two $200 bills, or $300 in the form of a $200 bill and a $100 bill, and quite frankly, I'd rather carry one $200 bill over two $100 bills as well. Just like as I said, if they bring back the $1,000, $5,000 and $10,000 bills some day, they need to issue a $2,000 bill as well. And hey, Europe has the 200 Euro note, so why can't the U.S. have a $200 bill? Also, all of the people who want Ronald Reagan on a coin or bill could have a Reagan $200 bill, and keep William McKinley on the obverse and the "denomination in circle" reverse just updated in design on the new $500 bill. And make that big "500" in the circle out of color shifting ink, as well as a few objects and numerals on the front out of color shifting ink. The $200 bill, like the $500 bill is also another money saver, to print less $100 bills and to make it easier, faster less bills to haul around, and more convenient to make change for $500 bills in places where they deal with large amounts of cash. Like jewelry stores and coin shows.

I think the US bills are easily counterfeited on purpose to give secret service more funding. Polymer bills would end the monopoly Crane has on US currency.

I hope that a future US $2 coin looks nothing like our coinage because they are not the same currency. It's bad enough that pennies, nickels, dimes, quarters, AND $1 coins seep past the border. They ( US coins) get in the way, your coins are filthy to touch, and they simply don't belong. You wouldn't like it if we exported all of our quarters to your country.

I would! but then again I can see why it wouldn't be reciprocated, your coins are way cooler!

The one dollar coins will take hold the day after they discontinue the one dollar note.

"You wouldn't like it if we exported all of our quarters to your country."
bit of an overstatement I bet its a very small percentage of minted US coins that end up in Canada in circulation. To answer the question itself though, not all of them but I'd love to see more Canadian coinage in circulation in the us. I like and keep all foreign coins I find. The only downside to me is the false alarms when looking through rolls of US coins for silver.
