This may not be very apropos right now, with a pandemic going on and all, but I'm thinking of travelling overseas when it's safe again...Next year or so, hopefully. I haven't decided where, so I'm just searching for what to see in the meantime, looking up on (and adding entries to) Atlas Obscura and such.
So, I was wondering, can you tell me about some numismatically interesting places to visit? Any country's fine, from museum collections and coin-related monuments. I just need ideas!
Some places I can think of -- but have never visited -- are the ANS (New York), the Numismatic Museum (Athens), the One Million Cent Pyramid (Vilnius), "Pennies from Heaven" (Virginia), Dukatenmännchen (Germany), and the Big Nickel (Ontario). I saw some of the Brussels Coin Cabinet's collection and visited the museum at the Monnaie de Paris last year, but apart from those, not much internationally so far.
In Tokyo, where I live, I've been to a few historically important sites, such as the Kameido mint (1668-1683) and the Ginza mint, but the only indications of their existences today are easily missable monuments. The Currency Museum adjacent to the Bank of Japan's headquarters is probably the only numismatic museum in Japan, too. There could be more, though, I'm not sure.

Outside the metropolis, I visited the Wado ruins in Chichibu some time ago, where high-purity copper (nigi-akagane) was mined in the 8th century and the first official coinage in Japanese history -- the famous Wadōkaichin -- was minted. Like Kameido, the site is commemorated by a cash-shaped monument, and the site of ancient surface mining (roten-bori) has been preserved. Nearby, there's also a Shinto shrine (Hijiri Shrine) where the nigi-akagane was first discovered.

According to folklore, if one washes their coin in the stream flowing near the Wado ruins and offer it at Hijiri Shrine as saisen, they receive good luck monetarily. Similar beliefs (called zeniarai) can be found all across Japan, including the popular Zeniarai Benten Ugafuku Shrine in Kamakura.
Anyway, does anyone know any place like that? Any coin-y public art, or preserved remains of ancient mints, or must-visit numismatic collections that you know of?
