You have a few different ones there!
The first row are Bully figurines. They are fairly plentiful, but mostly originate in Europe.
The second row are Comics Spain (which are more my forte!). I probably pay higher than most people on these and I will quite happily drop $25-30 on one I don't have. Most people I think are more willing to pay $15-20. Incidentally, I don't think I have the blue one, although I can't quite make out the symbol to confirm.
Third row, plus Peachy on the fourth row, are Portuguese necklaces/keyrings. Appear to have been sold both ways. These vary depending on which one. The adult seas are VERY rare. I paid a lot for my one like you have (mine is the necklace version) and the other adult seas have sold very high as well, but don't know how many people are willing to pay those prices ($60-80 I think). Next rarest are the baby seas. Think I paid around $30 for my baby Sea Shimmer, but have seen them around 35 Euros. The others are often listed high on ebay, but rarely sell at those prices.
The Medley I think is a necklace charm, but they're not something I know much about.
At one point there were a lot of the MIP Mummy Charm bracelets from the UK, which is when I picked mine up for about $5, but what happened to them I'm not sure. Positive it would be worth more now. I'm assuming it's the UK version with the metal bracelet, rather than the US with plastic?
