I have a strange feeling that the new $10 bill is likely going to have the lowest circulation for any $10 bill ever issued. If no bank in NL orders $10 bills anymore, some media outlet is going to expose the information, and will prompt residents to hold on to their $10 bills as collectors' items.
I also wouldn't be surprised if the new $10 bill will probably have a very short life, and possibly be the nation's official last $10 bill series ever.
I personally think the reason why banks are not ordering them anymore, or ordering limited quantities, is because low demand for the $10 bill may have caused the cost to order them to rise so much, the banks realized it was probably a lot cheaper to order the same amount of money in $5 bills than fewer $10 bills, and the banks are obviously going with whatever is cheaper and more useful and economically feasible.
If the new $10 bill never gets ordered by NL banks, it wouldn't be the first time a new banknote was never ordered by banks in NL - the 1988 issue $1,000 bill was the last such new bill, released in 1992, and was never ordered by any bank in NL. Rightly so, since it was used in organized crime.
The $10 bill is a completely different story. Low demand is what's putting our beloved purple banknote on death watch. If the $10 bill is no longer being printed, when purchasing power of $5 becomes $10 in some years' time, I wouldn't be surprised if the number of $5 bills in the nation will double, or more than double, and may prompt the need for a $5 coin if the number of $5 bills grows so much.
Keep in mind that we lost the 50-cent coin back in the 1960s. Demand dropped so much, possibly due to inflation, and the coin had since been deemed redundant, and even when purchasing power of 25 cents became 50 cents, the number of quarters in circulation supposedly doubled, or more than doubled. The reason for the 50-cent coin being redundant is because two quarters make a 50-cent coin, and two 50-cent coins make one dollar. The $10 bill is in the same predicament, since it is exactly half of a $20 bill, and exactly double of a $5 bill - because of this, $10 bills are considered redundant nowadays, and many banks across the nation have likely identified this in recent years.
I think the $10 bill would have been more successful if there had been a $25 bill instead of a $20 bill. A denomination of 10 does much better in cents, since there is no 20-cent coin; but won't succeed in dollars as long as there is a $20 bill. It's surprising that some banks waited this long to finally discontinue ordering $10 bills, and some banks were already ahead of the game as far back as the 1990s.
