Advice on selling vintage PC games

[deggles]

New to this area of the forum, so hope this is OK to ask! Is anyone familiar with the 'vintage' game market in the UK?

I have some old PC games from the nineties, all mint+boxed, tucked away in my loft. I keep thinking about selling them as at least one of them I believe may be quite rare and sought after for collectors. I know I could try eBay but just wondered if there are any specialist marketplaces or shops that might be a better bet?

I'm not desperate to sell but seems a shame they have been sitting in a box for 30 years when a collector might enjoy them
