One other note. Here's a photo of the coin market at Charing Cross Road, London. It is held on Saturday on one level of a parking garage not too far from Trafalgar Square. The entrance is a bit of challenge to locate, but it is worth the effort, and it is a nice way to spend a Saturday morning in London, before visiting the museums and other sites. Here are a couple of links regarding the market. My visit in 2017 revealed a nice diversified offering of world, British and ancient coins, as well as paper money. It is a small venue and the people there are wonderful! https://charingcrossmarket.com/ https://www.hammeredcoinsofengland.com/charing-cross-collectors-market-londons-best-kept-secret/
