Allis-Chalmers 718H

Hello everyone  this is my first day here!!! Well I am the proud owner of a 1974 Allis-Chalmers 718H. I have been trying to find out what this little bad ass is worth. I got this animal from my mother in law, now one would think that your in-laws might give you a little break on it. Nope she worked me like she owned me, bless her cold little heart. Some info on Allis, It's in really good shape, has original 18hp k361, I replaced all the deck spindle bearings, belts, new carburetor, new starter, new battery, took the mechanical fuel pump off and installed an electric fuel pump, the seat was all tore up so I replaced it with one from England ( got it from my brother ) This old girl has the same tires that she was born with, yup original tread. It's not that I want to sell her ( my wife wishes I would, she's jealous of her, LOL )  Oh almost forgot I installed a chrome skull with red eyes on the throttle lever, now that's classy I think. So does this old girl have any monetary value? oh and it's a 48" mower deck. any and all thoughts spoken out loud to me would be greatly welcomed, Sincerely, I thank You All.
