I’ve seen some crazy price ranges (mostly asks) for these and I know they don’t come up very often. I scored this one almost two decades ago. The bubble is cracked on the top but the figure hasn’t been removed. What is a fair value on one of these today?
That's going to be tough to value because that damage can be very off-putting for a lot of collectors. Personally I consider badly cracked bubbles to be likely to eventually deteriorate leaving you with a nice cardback and a loose figure.
Your figure has very large crack in the base plus a larger crack across the top. It also looks as though the plastic has melted across the top of the bubble. I've seen better quality ones with cracks in them sell recently around the $4k - $5K mark. I'd consider somewhere around $1k to $1.5k for yours due to the severity of the damage but it could sell for more to the right person.
