While not all that valuable, here is a machine I picked up a couple of days ago.
It is a Pace Orange Front Comet. The Pace Orange Front is a gold award machine and they are actually pretty hard to find.
Anyway, I got a lead on this machine. It was in Denver. When I was talking to the owner and looking at the machine I asked him if it came from Montana (Montana machines are typically in good shape (no humidity) and Montana was a huge Pace area).
The owner looked at me and said how did you know? After talking to him more I am 99% sure this machine came out of Butte Montana which is where I grew up.
To make a long story short, I bought the machine and the original stand that came with it.
This is the way to find them, all original, no rust, and old money in the jackpot and original Pace Gold Awards in the machine. Original Pace gold award tokens are next to impossible to find.
Here are some photos. I have done nothing to the machine and don't intend to. It plays great and it has entered the black hole (what some people call my collection because once a machine goes in it, the machine never comes out).
