Believe this is HK331.  Reeded edge.   Any info on if dbling like this is normal on this?

Quite common for cheaply made medals and tourist tokens.

That does look like the HK-331 1905 Bronze L&C Commerative medal ... https://www.pcgs.com/coinfacts/coin/1905-medal-hk-331-bronze-37mm-lewis-clark-centennial-expo/642750

Not "normal", but perhaps a little more common than say on circulating coins of that era due to less stringent controls.  But it appears to be the "worthless" type of shelf-like machine doubling ... https://doubleddie.com/144801.html

I agree that this is a form of mechanical doubling. It is step like in appearance and not at the same height as the rest of the fully struck image. I also do not see any notches where there are corners.

Looking at a few examples, it looks like it might be the HK-331. Someone better with medals might be able to give you a 100% on that.
