the DY is pretty common I think next to the floral it was the second most produced JEM (I think the 7VWH might be challenging that now).
I own a VDY which is much, much rarer. I would say for a mint condition DY between £800 and £1000 is about right (I would guess this as being around the 850-1100 Euro figure).
HOWEVER, if it has wear on the fingerboard (dark patches) and chips etc pay no more than 800 Euros, also check if it has the old
Edge trem. You can barter him down if it has as spares are not that easy to find.
If its a 1991+ it will have the Lo-Pro edge which is superiour. Also be aware the original JEM neck is much thicker and wider than the modern and it will have the original
neck joint which VERY noticable at the 17th fret, be aware if you have small hands!
Also check the gallery here to make sure he has not changed the pickups/knobs etc/ Faded pickups is another battering point, I am lucky in that all 3 of the pickups on my VDY are exactly the same salmon pink colour.
Hope that is helpful to you
