Ah, the mystery of the "Nintendo" mold…

LAZY "N" (a/k/a OIL CAN MOLD) -- 8 N's or oil cans. A recently discovered old mold. Distributor is unknown. It's a real mystery -- it wasn't made by the Burt Co., which manufactured most of these old chips. Steve Goodrich provided the scan..... I have recently picked up a number of chips with this mold, including this one for bpoe Elks Club lodge 1907, Rangely CO (only one chip).... Ah ha, maybe the "N" stands for "Nintendo." In August 2014 on
eBay, 100 of these chips appeared in a cardboard chip box, printed on the box is "Nintendo, made in Japan." Everything was complete and in mint condition. The chips were plain white, with the "Lazy N" mold. Here is a picture of the chip, the Nintendo box and the "N" logo of Ninendo, which appears on the box. Nintendo was founded as a playing card company, a product it still makes. It is the largest video company in the world by volume and the third most valuable company in Japan. ....... The ones I have for sale are hot-stamped "MCL," are in very fine condition, colors: red, white, blue, yellow. I also have plain white. Some others have on them SOR (or SQR).
My google-fu also revealed someone’s blog site where they bragged about snagging boxes of these at a thrift store for $1.99 and then reselling them for $30+ on
eBay.

This one is particularly exciting. I believe I got 40 of these poker chip sets at a thrift store for
$1.99 each. I have already sold four of them for
$30, $30, $41 and $28! I have already made my money back and I have 36 more sets to sell!
