While very rare, I think that there are more than 50 of these games in existence. I know of at least two collectors that have multiple copies of Voltan; and they do not post their collections on the internet. I think the rule of thumb of number of games that still exist is halved every 10 yrs only held true prior to the home collector market began to grow in the 21st century. I think one needs to adjust in years post 2000 that the attrition rate is about 1% per year. Also I think that one of the reasons they only made 365 of these pins, besides maybe not testing well on location is that Bally wanted to utilize the production lines for games that were selling better or in more demand Like Playboy, Star Trek and Kiss at that time. I love my Voltan, but more for the artwork package, not so much for game play. I kinda wish it had chimes instead of electronic sounds, as this game has more of an EM feel to it.
