These are worth something.

The values for these boxed sets, know as "gold boxes" can vary greatly.  If they are mint and shrink-wrapped, you might get $75 a box for the smaller boxes and $125 for the larger boxes.  If there is no box, or it's beat to hell, the miniatures are painted badly, or are banged up, or you are missing even one figure, you might get $10.00 for a small set.  Unless the paint jobs are pretty good, painted figures are actually worth less than figures which were never painted.  Inserts are more important for value purposes than you might realize.  A complete box set with an insert might go for double than a box missing it.  Make dang sure you don't have a gold wizard or orc shaman figure in your mix.  Those miniatures of real gold are worth $100.00 just by themselves and are very rare.

These figures do contain lead, so wash your hands after touching them and make sure no small kids get near them.  If they are completely painted, including the bottom, they are safe to handle.

Just looking at your picture and text information, I'd guess you'd get $8.00 to $15.00 for each set if sold separately.  Your last two sets, even with missing pieces, are likely worth the most.  If sold in one lot, I'd guess you'd get $50.00 for them this summer and $60.00 during January and February.  

A good place to look up D&D licenced/approved minis is DnDlead.com. Look to the proper link on the right of this (Grenadier) page for the type of box you are looking into.

The 'gold' minis aren't really gold, just colored that way via plating of some kind. Sorta like the 'golden' dollar coins we see nowadays. Just an alloy that looks a gold-like color.

Grenadier had run a promo where some select boxes had a 'gold' magic user, orc shaman, or I've also seen a basilisk. In the box, there was a coupon that you could send in for a raffle of an ounce of actual gold. There's one on EBay now for a look-see.

Glad I found this thread! I acquired a box of the Fighting Men and Specialists (in box with sheets - 1 fig missing from Specialists) last summer and haven't had any idea of the worth.

Thanks Blackmoor! That's about what I was guessing - they were with a bunch of 1e books and an older Basic set (still with the wooden dice) that I picked up for $10.

Only a great deal if it's something you want or need...and definitely don't need or want these...
