the bills will have tracking tape in them and old bills will be exchanged by a TBD date or worthless. They want to know where all the cash is.
Overheard a stranger discussing this on his cell....Time will tell if true...
Consumers and businesses will not have to trade in older $100 notes for new ones. Older designs of Federal Reserve notes remain legal tender, and will not be recalled, demonetized, or devalued.
What a relief, the older bills have a classy look vs the new bills (all denominations) that have that 3rd world money look.
I'll have to round up a few thousand old C notes for nostalgia sake.
