Dan Wickett has Bianca's Corral listed as a Route Token:

Dan's prices can give you some indication on value.

Didn't know there was such a site, thanks for the help. I think it's been awhile. I can't even find my Chip Rack or Chipguides. There here "somewhere" or maybe in the garage or the storage unit.

I looked and I have one with reeded edges, so it's 1991.

Which one of the Castaways is this? I can't understand the mint mark?

Looks like CT but it's not listed CM is.
