Tigervision Prototype Polaris - Not sure about this. Help please.

[Atari Matt]

So I came across what I assume is a Prototype of the Tigervision game Polaris. I can't seem to find any other Tigervision prototype cartridges like this to compare it.

 

What exactly is it?

 

What is a realistic value for something like it?

Probably a cart sent out to reviewers in games magazines pre production, with the ROM being swappable for future games to be reviewed before release. Nice item!

It's legit.  That's the programmer's handwriting on the label and the date matches up as well.

It's a sample cart so it's more than likely the finished game. Normally I'd say these go for $75-100 but values have risen and this is a fairly rare game so it will probably go for more (maybe much more) than that.

The known prototype dated 2/17 is sightly different from the released version.  This one is dated a day earlier so it's probably more or less the same as that one.  The only way to find out is to plug in the cartridge and try it out.
