I will take care of the mintages later. They are incorrect anyways. Plus will create separate pages for trial strikes

@farkyyy   are you OK if we proceed with these changes?  Normally we do not split out year lines for different mint packaging of the same coin on a coin page (only for sets), so merging is appropriate. 

Yes. the change is appropriate. thank you very much!

Done.  As requested, mintages have been left as is.

Thank You
