I remember when these computer vended postage stamps first came out in 1992. One of the members of our local club went to one of the test sites and came back with a boatload of $0.01 strips (initially the machines would print any denomination, but later due to losing money to all the $0.01 values being printed for collectors and dealers, the machines were adjusted to only print denominations of $0.19 and up).
I still have a bunch of those $0.01 plate number strips from back then, but I ran across this item in a collection today. It's a plate number strip of 5 without any denomination printed on any of the stamps.
Scott does not have a listing for this. Scrounging the Interwebz, I see auction listings for occasional items showing shifted denominations where 1 stamp out of 3 or 4 does not have a denomination, but I have not seen any examples where an entire strip has no denomination, let alone a plate number strip.
Any value or is it just an oddity?
