case xx magicians' knife

[400 horse]

can anyone tell me what a case xx magicians' knife might be worth? i found it the other day. It's in great shape. it has case 6220 1/2 on it. It also says 1 of 1000. Any help would be greatly appreciated.

Might have better luck in the traditional forums. There are some real knowledgeable guys over there. I have never heard of a Magicians knife - would love to see a pic
