I was just discussing this with a friend the other day...hard to tell but I would guess maybe 25-30% more than they are selling for today? The 87's are 25 years old now. I'm thinking all the kids that wanted them in the 80's will be nearing retirement age by then and the demand for them will be higher. Probably more so in the 15 year time range. As for how many left, I would guess much less than half. Lots of them ended up as drivers (i.e. crashed, stolen, parted, etc).
