1999 founded Team Rensi motorsports NASCAR owner collectible challenge coin

1999 founded Team Rensi motorsports NASCAR owner collectible challenge coin. In very good condition. I've had it in a curio cabinet on display since I got it. But due to some unexpected medical bills for one of our children we are downsizing our souvenirs and collectibles. I'm not a coin collector but I got this many years ago and I haven't seen one like it since. I tried to look up and research online but had no luck finding this exact coin or challenge coin. So I'm assuming this is a very rare coin. So I hate to have to sell it. It weighs .5 oz Very solid and feels a lot heavier than it's weight.
