I picked these two chips up at a flea market today. The are labeled as being from the State Line Club on the Montana - Dakota border. I looked this mold (MD-42) up on Robert's site and it would date them from the early to mid 1950s. I did a google search and there is indeed a State Line Club in Montana but not sure how long they've been there. Any idea on value?

Nice to get a "new to me" mold....
