From the Polymerbit notes collection I built up in the last years you'll find retail-prices (= upper limit) for some of them here:
https://www.coinsofnakamoto.com/collectibles/notes/Some notes are worth just 10 bucks (like the garlic & via notes), most notes are between 20-30 bucks (like the LTC, ETH, 1776, bees, triangle, 1/10th, 1/20th, Test & Custom).
The Monero note was sold recently here on the board and from what I see just a few could be worth more, like the blue 0.1 BTC note... see link above!
I bought most of my Polymerbits in bundles, averaging at about $25 per note of the notes I see in your pics.
I can't tell you prices for the notes I'd be interested in (red 1 BTC, violet 20, orange 100, brown 200, blue 10 MBTC... sry for the abbreviations used) but I wouldn't pay more than the $25 per note already stated, maybe $50 for the red 1 BTC. But that's just because I like it and I don't have it yet.
Edit.
Of course: price estimates are for unfunded notes.
