i have a duncan glow imperial and i was wondering how much it was worth
like 1 dollar. not even joking.
thats less than a normal imperial… 
Used Duncan plastic unless super mint and retro only sentimental value. My kid sold one for $5.00 but that is rare, seeing as most party goods stores sell new ones for that.
its from the 70 s i belive. it has the old duncan logo. not mint.
Couple of bucks to the right person. Finding the right person… Probably not worth it.
