I've compiled a list of the coins that I've been led to believe after some internet searching on each individual type of coin. Some (like the swedish gold coin) I'm sure is worth a fair bit, the rest I'm less certain about. Would be great with some extra opinions before I approach a coin dealer, so I know what I'm doing, at least to some degree.
I will produce pictures of any/all coins upon request, but i'd rather not completely flood the forum with pictures from the get-go, especially considering how new I am.
Also, there are quite a lot more coins, which I've pretty much already dismissed as useless (like franc from just before france switched to Euros, modern british coins etc.. Feel free to ask about the rest in case I did overlook something.)
Edit: I have updated the lists details according to Matteproof's comments. Thank you for correcting me.
