Rare discs look good on the wall and may help lower your scores. I prefer throwing fly dye for the colors and collecting old discs that
A: catch my eye with a cool stamp or
B: I think I can sell for a small profit.
I have 500 fly dyes and some unusual older discs you can view/purchase/ make trade offers (see website below). I am unfortunately a habitual golf disc collector and have many boxes full of discs that I just want to keep....this stash rarely sees the light of day and includes tournament stamps of places I've been...3 discs (CE Valks) from Players Packages at the first USDGC, Climo 3-12 Time World Champion stamps with his autograph, most of the Champion Rocs that exist and on and on...I look at it in the light of ball golf....50 years from now they might have real value but now they are just cool to have...I might post pics if interest is shown...let me know if you want to see 'em...
