I walked in there today wanting to sell some bank notes. One in particular note (1954 $5 devil's face) had stated the value is $525.00 on the website. I knew I wouldn't get that amount before going in because it was folded once, but I was expecting to leave with at least $300.00. The clerk, as stated in the comment written before me, literally went through everything I had in two minutes and said "face value". Don't know why I wasted my time coming going in there.
I brought my collection of Canadian and world banknotes to ACC to sell, some 500 in total. The clerk took less than 5 minutes to go through the lot and then offered me $514. I did not point out that the face value of the Canadian bills plus that of the convertible foreign ones far exceeded that total. Why bother. Rather i told them that i would give the bills to my grandkids and they could come in when they are my age and sell them to his grandchildren. But really, that was an insult to my intelligence. I mean, on their web site they were offering for sale one of the bills i brought to them for $700. And taking only 5 minutes to go through so many bills was a rude slap in the face in that there is no humanly way to properly evaluate a bill in 2/3s of a second. Heck, it was done so quickly that the clerk could not even tally up just the face value of it in order to offer me at least that much.
As for their selection of coins, it is excellent. However, you will pay through the nose. But i suppose that is how it must be if they are to continue paying what must be an exhorbitant rent for their 5 star location.
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.
