They used these chips in the 1970s when the Frontier was located in Vancouver, then brought them along when the club moved to La Center and became the Last Frontier. They used them up until about 10 years ago. There are actually two varieties on the 1.00 inaly--one says simply "Washington", the other "Vancouver, Washington". Do all the quarters have the same inlay? I've never seen the second version in the 25c chip. Good find!
