This first coin is already ID' and on the Obv. there is Tyche an The word CARTEIA around the rim in large letters, on the Rev. is posiden with one foot on a rock and he's holding a trident in his left and a dolphin on his right. a similar coin can be found on wildwinds http://www.wildwinds.com/coins/greece/spain/carteia/Villaronga_71.jpg but i'm still not sure what the value of mine is???? The other coin also from Carteia and on the Obv. there is a head of Jupiter and on the Rev, there's a dolphin with the word Carteia below. I think this is the same coin but i'm not sure http://www.s110120695.websitehome.co.uk/SNG/sng_reply2a.php?verb=SNGuk_0902_1728 i'm not quite sure about the ID so feel free to prove me other I also have no idea about the value of this coin because the only webstie that has it (link above) doesn't have any values? (the coin pictures 1667,1669 are for the second coin metioned, and 1675,1676 are for the first coin metioned)
The coin you linked to from Wildwinds sold for $41. It is in a bit better shape than yours, and also sold by CNG though. Here is a link to website that offers some Celt-Iberian coins for sale, but as far as real worth, you would probably get a better idea from E-Bay. http://www.artisopusgallery.com/coins/Iberian/index.htm
