I need some help deciding on a fair offer for these 1/24 tank models

S o a buddy at work ended up having this and wanting to get rid of them. bandai 1/24 scale panzerkampfwagon-V panther g and panzerkampfwagon-VI king tiger. also a DML 1/35 M4A3E8. My best guess for the two bandai kits is that they are from 1973ish. These are not the RC kits. panther seems to be missing the tracks otherwise it seems they are complete. the decal are pretty much a write off. boxes are in fair shape and i must say outstanding instructions in color! fun fact still has the price tag on them of $19.97 lol.







I still cant get over the sheer size of these things. also if any one has built these before let me know any tips/ problems you had
