in the UK you would get max £5 to £2 each for them. unfortunatly there is nothing rare there
now if you had a MGS3 or ZoE in there.. Ico or SotC might of got you up to £10-15.
you see a game like PS1 Star Ocean 2 could set you back anything between £80 and £100, which is totally mad.
the only game i have that i never sold because i think its really worth something (apart from Star Ocean 2) is my ltd ed Wipeout for PS2...
a friend of mine used to know a PR agent who use to promote games, and he had one of nine ltd ed hologram Wipeout boxes.. its basically the game with a press release disk but the box is the pic of the normal box, but in a 7 phase hologram (which apparently is rare in itself)...
anal... me? lol
anyway, enough of me... Coty, if you sell em all, you might be surprised then again you might be dissapointed, but if you trade them, you will get a better price!
