It could be worth a few hundred to a haro collector the market is a little influxed with mid to late 80's though, i bought a restored 86 Master a few years ago (i no longer have wish i did) for 450bucks 80% was NOS. Nice bike though it looks all original and in good shape.
I have a 87' Haro Master with Peregrine 48 wheels. Its the teal color scheme...anyway same bike about year ago sold for $1000.00 on ebay. The bike was in preetty good shape, normal where and tear but nothing major...
I remember hearing from a collector that the '87 was a tougher year to find. It was his favorite and he was always on the lookout for them. So I'd guess you could definitely make some money if you don't feel attached to it.
I thought the '87 had a painted frame all the way to the chainstays/seatstays and chrome extending from there to the dropouts but maybe I'm mistaken. Either way for a bike that old it looks great.
