Ive got the chance to buy these 4 cars etc.They are in NM to Mint boxes.Dodge Dumper #48-Hoveringhan #17-Grit Spreading truck #70-and the Pipe truck #10.All of them are 15.00 a piece.Is this a good price?All are Mint in Mint boxes with black wheels.Thanks,Sprinter

Yes this is a very fair price.These are not the most in demand castings but they are all beautifully made.If the Matchbox name on the box sides is underlined in black then you have less common desirable F boxes rather than the common E boxes (matchbox name is printed in a gentle bridge like arch)
If you like them buy them ,but given fees & shipping,there is not much profit to be made putting them on ebay or ttp
