There are a few small coin shops, although stamp dealers outnumber them.
In the warmer months there are flea markets in the Rembrantplain area, a number of coin and medals dealers set up there.
On Saturday mornings there is a small coin and stamp group that set up under tents on the sidewalk just outside the Amsterdam Historical Museum, just outside Dam Square in center city.
Group antique shops will have a few items to peak your interest.
Its a fantastic city, easy, very easy to spend way to much money in on antiques, books and coins. Keep in mind, that US coins are in the foreign box.
