On sale February 19th: https://catalog.usmint.gov/americas-founding-fathers-2019-currency-set-B15052.html
When they say "product limit: 5000", they mean they gonna produce only 5000? I ask because they also say "mintage limit: None"...
It means they're only going to sell 5000 of this product, but the same coins/notes used in this product may also appear in other products at some point.
I'm not going to spend what they are asking just to get a one and a two dollar crisp note with matching serial numbers. Oh yeah, and a nice cardboard holder for those notes.
