From the Polymerbit notes collection I built up in the last years you'll find retail-prices (which is the 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 are 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, brown 200, blue 10 ETH... 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 (just because I like it and I don't have it).
