A longhsot indeed, but you're in luck.
I was randomly going through some old bookmarks and I came across
an old ebay auction for my cards. I have all 3 sets, unopened, and I never sold them. It was always so crazy to me that there were 3 separate contests, only 1,000 sets of each, and I won all 3. I only put them up for auction once and I wasn't gonna let them go for cheap. After such a lackluster interest, even after advertising on the official Namco Tales forums and everything, I didn't bother to relist them...
I know they're rare, but how do you put a price on them? What is their inherent value of 3 sets of 1-in-a-1,000 all together in a complete set? And who even really remembers them or wants them?
I decided to Google to see if there was anyone looking for them and I came across this thread... I was surprised to see that it's only 5 days old.
Anyway, a pretty penny you say? How pretty? Because, I don't know... I mean, it'll have to be really pretty if you're breaking apart a complete set.
...I think.
I kinda want to help you out, but this thread may just, in the end, spark my interest in relisting them on ebay (and re-advertise them on various Tales forums) with a crazy reserve to see how much I could actually get.
