One of a kind? Chase the Chuck Wagon, w/ box, Instr. AND coupon used to get the game

[rbudrick]

I have a complete copy of Chase the Chuckwagon. Now, I know this game is not nearly as sought after as it once was, but it is a complete copy, whcih is pretty darned rare. It has the single instruction sheet with it too.

On top of this, I have the only copy with an original coupon used to send away for the game...the coupon that was in the dogfood bag back in the day.

So, what is a complete copy worth?

What's my copy with coupon worth?

I know it's a just a damned piece of paper, but that often doesn't mean a thing to collectors if it's OMGwtf r4re.

How may known people actually have complete copies of this game?

Opinions?
