These games are all over the place lately. I currently own three and have had a few others in the past.

Like others are saying, completeness means everything as many of the specific parts (backglass, moulded scenery, etc.) are unobtanium.

In the past two years, I have paid $300 for a non working Williams gun game and $750 for a fully working Chicago Coin game.

I think a complete, non-working project should range between $400-$600 while a working example 100% playing (not full cosmetic resto) would be between $750-$1000. Obviously some titles like Midway Haunted House garner more, but this is the range I see.

Here is a link to the Morphy auction listed above. Some of these arcade games went for insane prices IMHO.

I think ones from the 50's command more. I know more common games like Arctic Gun, etc. seem to be in the $500-$600 range. I sold a full playing, 8 track included, Midway Wild Kingdom for around $700 around three years ago but it is a more desirable title.

I was hoping to see a nice restored Midway Sea Raider in those auction results. I have been debating doing a full restoration on it but just can't justify it.
