Hi and welcome to Pennymachines.
Congrats on your machine.
The members here are very helpful with solving problems and sourcing parts, but we tend to avoid quoting values as it is so very subjective. What a machine is worth is so dependant on a mass of things that may have happened to a machine during the last 50 years. At the very least many detailed photos are essential.
If you are looking to sell your machine we don't allow adverts in the Forum.
We have a Market for that
I note you have already been asking your question on Facebook and the advice you're being given there is pretty much on the mark.
Including the post I put on there about 45 minutes ago.
