Royal Mail Presentation stamps packs

[MrsCatBasket]

Posting in AIBU for footfall as I'd really love some ideas, please.

Over the past 10 years or so I have been intermittently doing research for a company who are employed by Royal Mail to check the ongoing efficiency of delivery times and the condition of mail when it arrives at the intended destination. I don't earn money, though I do get 2 books of first class stamps for any month of research that I take part in. Intermittently I also get a presentation pack of collectible stamps as an extra thank you.

I now have several collections that are sitting on a shelf, all forlorn and unused. I would like to do something with them - but what? I've been bitten by ebay's unfair policies more than once so I don't use it for selling. I could just open them and use them as actual stamps, but that seems a waste.....any ideas anyone? I will attempt to add a photo of the type of collection I mean

Do you want to make money for yourself from them? If you don't mind about making money, you can donate them to some charities who then sell them - I know Oxfam have a stamps department and I suspect some of the other big charities do to (and smaller charities might sell in individual branches).

There are collectors' shops that specialise in stamps and coins (admittedly not on every high street!) that might be interested. Could be worth seeing about?
