Post 1947 coins (British and world)

[Magpie1]

Hi- I have recently started collecting and some kind friends of friends have given me small bags of spare coins from their collection. The only thing s that most of them are post 1947 and some are world coins (some pre 1947) and as far as I can tell none of them are more than a f/vf grade. I really can not incorporate them into my fledgling collection and wondering if and where I can take them to raise a little capital to fund some coins of my interest (shillings and half crowns typeset from each monarch is what I’m going for!,) Any advice appreciated

I'd suggest ebay might be your best bet, without seeing what you have. Things tend to find their level.
