City of Goslar, help to Identify, do you have this german catalogs? [решено]

Hello experts, 

I would like to add this coin in the catalog but I cannot to find any reference.

Looks like a Matthiasgroeschen from City of Goslar

I bought the coin with a paper with reference “knyph. 6015”

But this catalog is not in the Numista list.

Some coins from same period are referenced as

“Standard Catalog of World Coins (pre-1600) unpublished” If is unpublished, how do I find it?

There is also the catalog “Die Münzen der Reichsstadt Goslar 1290 bis 1764” but I do not have it to know the reference.

Anyone knows a reference for this coin?

23mm

1.67g

lettering looks like: 

Obverse: MONETA….

Reverse: MATHIAS SANCT

Any help will be greatful appreciated!

Thank you for any comment

This coin in the catalog N#151587 has a broad date range, and a search on acsearch shows numerous small variants.

I don't have any catalogs, but mine was attributed as BBK10 

There are also quite a few on MA-shops with catalog references assigned.

Thank you very much, looks like there is really several variants, I will add on my collection under the link provided.

Your help was much appreciated!

Knyphausen is from a Collection of a numismatic collector of german Nobility.

sold his coins in several auction and his collection is used as numismatic reference.

here what some of it looks like, a rare book I believe.

George S. Cuhaj (editor); Standard Catalog of World Coins (pre-1600) (unpublished). Krause Publications.

has the same link and abbreviation "MB" as 

N. Douglas Nicol (compiler), George S. Cuhaj (editor); 2011. Standard Catalog of German Coins / 1501-Date (3^rd edition). Krause Publications, Iola, Wisconsin, United States.

which is published and available. However all it says is

But it does reference Saurmasche 3961, which is here

The Saurmasche site is great because they cross-reference the details, for example to list all the site's “St. Matthias” coins.
