They have been around for ever, and have now moved into an office tower, but Arcade Coins continues to offer a good, varied stock of coins and paper money. Their greatest coin strengths are in the Canadian decimal series, as well as ancient coins. Grading is generally refreshingly conservative (particularly on paper money)--if anything, they are prone to undergrading, particularly on the lower-priced items. The security systems can be a bit off-putting at first, but the knowledgable staff can be quite warm, particularly once they accept that you are serious about your collecting. The days of the bargain binders of world coins vanished when they left their street-front location a few years back, and the emphasis is increasingly on medium-to-high-end collectors. My only real complaint is that they are generally no longer open on weekends.
