You can also check the difference between real Doubled Dies and worthless doubling on www.doubleddie.com which is an excellent teaching site.
Hi Imho, it looks mad ( misaligned die strike) please also check out the above websites as mentioned by @thomas mozzillo . Lots of great information there. Nice b/w pics.
Could both the obverse & reverse be a misaligned die strike? I see the rim misaligned on both front & back
Yes ,it is possible to have the hammer and anvil die to cause a dual misalignment. Check this website on mad. Interesting write up. http://www.maddieclashes.com/dual-misaligment-of-the-hammer-and-anvil-die/
Ok so I'm thinking this coin may be the same thing... But what would these dots on L side of obverse be from?
