I will be sailing to Alaska on a June 21 poker cruise for the 4th time.
Check the antique stores in Vancouver. I find lots of chips there.
The antique stores in Alaska are very high. I have found a few old "Alaska in trade tokens". There is one shop in Ketchikan that specializes in them.

The scanned one was from a place in Anchorage called "Bingo Darts"

Yes, there are private clubs in Alaska that have poker. They do satelittes for the WSOP every year.
