Update Hendin reference [solved]

First of all, I basically know nothing about this topic and these type of coins. But I noticed something that needs to be updated sooner or later, and that's the Hendin reference.

Currently, it's on Numista in the form of the 5th edition. And last year, the 6th edition was released. Problem is, that a lot of reference numbers were changed. Last year some auctions listed the numbers for both editions like this one.
But now, it's just the new one I guess.

So this is not only a request to update the reference in the database but also an appeal to people who have that new reference to correct the old numbers in the catalog (which sadly is a huge amount of work I can imagine). And I don't think there are a lot of people with that reference.

Hello, thanks for the request. I've added it here:

When the reference numbers are different, we keep all editions of the books, see for example Menzel.

I have this book, I might have a look at updating the numbers at some point.
