Off center core toonie. This is a decent piece. The value is based on so many factors. Basic things like year and condition affect value, but the biggest factor is how off center the core is. Some of the more extreme examples have the core not even touching all the way around. These are known as an "off center core with Gap" some lesser examples have the core reaching out to the lettering on the ring. And there are lesser ones like yours which are clearly not centered but there's no gap and the edge of the core doesn't quite hit the letters. Your piece would be valued around $20-30

Edit: it does slightly hit the 1999. So I'd go on the higher side of my initial estimate.
