Where would you sell a collection

[MadeInEngland]

A few years ago my father in law died. He had a collection of model cars, buses, lorries of all different types and sizes. There is probably 100-150 peices altogether. Some, but not all are boxed and some have certificates. Can anyone recommend a place I can take them to get a fair price for them only we are having to put the mother in law into a home now and we need to clear out her house.

Thanks for suggestions but ended up selling to a dealer who sells on ebay. Only got 1/2 of what they were worth but haven't got time or inclination to do ebay or car boot etc, I'm far too lazy for that.
Anyway all gone now except for the best ones which the family has kept.
