It's been my plan for more than a half century, allowing quick payment for coins...., etc., when an opportunity arises. It's real handy now when virtually everyone is reluctant to spend, interest loan rates are significantly rising, Fiat value is being diminished, and pre-33 MS69-70 Gold is priced reasonable. JMHO
I dug my 7 packs of $2 bills I had stuffed in the back of the safe years ago and 5 of the packs were in numerical order and 2 were mixed, so I pushed them back into the safe until I get really bored. Jim
Mix a $1 bill in one of the straps and offer it at a premium as a rare error strap, someone these days will buy it, you watch and see.
