Brussels coins and notes

Hello anyone know anywhere in Brussels city centre where I can find coins and notes?? I am heading there in December.  Regards Bren

Best bet is actually a flea market:

But there are also shops around, notably:

For very common Belgian and French silver coins also:

PM me your dates, if it works out always happy to meet up for a swap and a beer :)

Forgot to check my replies..😭 Thanks Colin.  Yes the market would be perfect for my low budget coin collecting!! 😍😍😍
