There are two coin pages:

which have this comment on them:
This coin also exist under KM#115 but it is the same coin, a mistake has been made in the Standard Catalog of World coins, creating a confusion. But these coins are the same as KM#34a.
If there is a mistake in Standard Catalog of World, then why do we have to keep it in here as well? Shouldn't we merge them?
