How to place a value when trading machines

[mrblatzman]

I need some input from some of you who may have had experience doing this....I have a very nice...not perfect...but a very nice original Jennings Favorite, minus the glass, but every other part is there...I like it and it is probably the "fanciest" machine in my collection, but my favorites lie elsewhere...I would like to acquire Daval Bell Slide, Clearing House, Rithmatic, and the metal Jokers....In you alls opinion how would be the best way to apply value across the board on these 5 items, and should a agreement come to light how could it be conducted where all parties are safe and secure? This may be a real stretch to ever accomplish, but thought I would ask...Thanks for any help or suggestions....Bob Reno in Fort Payne Alabama
