Authentic John Hammond Cane from Universal

[mosquito]

I have been trying to sell this John Hammond Cane I have been talking with Plasma Infusion site who is interested in the purchase he has offered 750$ US for this plus a Happy Glimore Putter....I can not find another one of these canes anywhere..It came from Universal Studios and was giving to an Executive who has died. Does anyone know of any other replicas ICONS never produced the prototype (This is what I think if have)The prototype in the picture of Hammond holding the can with the ICONS logo in the corner was borrowed from Universal as per Plasma Infusion .
Can any one give me a ball park figure on its worth.
