Numismatic shops in Berlin and Katmandu?

I'm probably taking to Berlin and even later Katmandu in a few months.
Anyone who knows of coin shops or antique shops which may have coins, in those areas? I'm only on walking legs, so in the center of the cities or around that area would be prefered.

I've looked at the outings on Numista, and only found one in Berlin.

If I get any suggestions, then thanks in advance :)

In Berlin-Friedrichshain are some Numismatic Shops (and antique shops). Depends on what coins you need, I mostly buy collector's accessories at Nowak & Beth.

If you have the time and the pandemic is not in the way, a stroll around one of Berlins many, many flea markets can be an option.

For example every Sunday at Ostbahnhof (East Train Station) or Saturday at Bode Museum. But dont expect treasures, i buy mostly buy cheap world circulation coins there. The flea market at Boxhagener Platz (or "Boxi") in Friedrichshain is mostly overpriced, but i had one lucky buy there.

Besides this many small antique shops tend to have one plate or box with cheap coins.

Kathmandu will likely have a few that are not listed and no doubt open markets that sell all kinds of nick nacks and weird things. Be on your guard for fakes and fantasies though. Anything touristy could be a red flag.

Also not sure if Nepal has an antiquities law, meaning you need a licence to take anything really old out of the country. May be a good place to find cheap old Nepalese, Indian and Tibetan coins though.

It is also a place where the women will dress with chains and veils of coins sewn or welded together - so could be fun. India has a rule on anything over 100 years can not be taken out of the country, not sure if its the same in Nepal.
