Hey guys, I just had 8 machines dropped off and I have been tasked with selling the machines for the estate of a pinball collector who passed away (I don't know his name). The 8 machines are TAF, LotR, PotC, MM (original), IJ, Elvis Gold, SWE1, and DE Star Wars. The 3 Stern machines literally look like they have never been played. They are all super nice. The Elvis Gold, for example, still has the goodie bag stapled inside and comes with the Certificate of Authenticity signed by Gary Stern and Steve Ritchie. The TAF looks like it when through a major restoration. Again, it is extremely nice and has a topper. The MM is in super nice condition as well. The IJ is in nice condition, but I did notice that the backglass has a corner of the glass that broke off (the translite is fine) and the cabinet has a couple of fairly large scratches on the side (the decals are still bright orange). The SWE1 looks above average, but it is not a collector piece or HUO. The DE Star Wars is in fair to average condition with some cabinet touch-ups (it is a French re-import with single slot coin door). So far, the machines were turned on and power up, but none have been tested yet. All of the machines had the balls removed from them. I am undecided on what machine to start looking at first, so I thought I would present the machines to Pinside to see if anyone has a specific interest in any of the machine. That might dictate which machine to inspect and test first. The estate is looking for fair prices (they are not giving them away or entertaining low ball prices). However, they likely will beat any current price for a comparable machine offered on Pinside. They are in the Los Angeles area and available to test and inspect. If anyone is outside of the Southern California area, I can post pictures in a Marketplace ad. PM me with any questions as this forum is too large to check for replies.

Any interest in a nice SWE1 and a rough Data East Star Wars for $5,000? The SWE1 is clean and needs nothing. The DE machine is a French reimport with a French coin door, rough cabinet, and playfield inserts that are listing. It works fine, it just needs cosmetic work. $5,000 for the pair. Pickup in the Los Angeles area. DM me for pics or look at the LA craigslist and LA OfferUp site.

Did you ever go to the C.A. Robinson auctions back in the early 1980's? Man those were fun. Wall-to-wall games for less than half their true value. Unbelievable deals and the staff was so nice. I don't recall there being a buyer's premium since the company owned all of the machines.

I am trying to unload the last 3 machines that I was commissioned to sell for the estate of a pinball collector. I have an Elvis Gold that looks like it just came out of the box. Comes with signed COA. Manual and goodie bag still stapled inside the cabinet. 2nd game is a SWE1, which is clean and needs nothing. 3rd game is a rough Data East Star Wars. This machine is a French reimport with a French coin door, rough cabinet, and playfield inserts that are listing. It works fine, it just needs cosmetic work. $11,000 for all three machines. Pickup in the Los Angeles area. DM me for pics or look at the LA craigslist and LA OfferUp site.
