I picked up a few of these yesterday at Pechanga. They are oversized (43mm) NCV chips. They are brand new and I have not seen them before. They are pretty chips and are the same on both sides, with a house mold. Since I "sacrficed" (haha) $5 in free play to get them, I will send one to you for $6 shipped in a padded envelope. I repeat, they are brand new chips.
Please email me directly if you would like one.
Thanks,
Rich Hodges
