Welcome to the forum
It depends upon condition, and how recently it has been serviced. As far as I know, no particular variation commands a premium although I suppose collectors might pay more for the earlier/rare plastic grips.
If you could post some photos, that would help judge condition.
Here in the UK, they seem to go for between £120 (rough) to £250 (excellent condition and recently serviced), more if accessories are present.
