I am unaware of any new ones.
Coin Mart would be the one in Coquitlam, and the guys there are fair to deal with (fair meaning honest and good communication as opposed to fair on your elementary school report card).
All of the LCS's mentioned in the 2012 thread are still around to my knowledge except it is called Chantou not Chandou.
In different ways I've found all of them good to deal with.
J and M has large inventory relative to the others in my experience, and is good for supplies as mentioned. The staff are knowledgeable generally. They also deal fairly in bullion.
Jim in Richmond is pleasant to deal with, and service oriented.
Joe at Chantou is also good to deal with, and is quick to know what he has in stock.
The Coin Mart guys I've dealt with a few times directly and through
ebay. They grade fairly in my experience (as do the others).
All Nations on Dunbar really has a niche business with a focus on their weekly auctions. Brian is very knowledgeable and nice to deal with as well. As a kid I shopped at his (father's) store when it was just below Pender Street downtown. The original sign is in the store front on Dunbar.
Those are the ones I know, but then I'm on the western side of town, so rarely get out to New West and Surrey etc. It's hard to go wrong with any of them really.
