Searching for Martin Luther

Today is Reformation Sunday so I tried to search the catalog to see how many times Martin Luther has been memorialized on coins. Is there a way to search for Martin Luther only and separate from Martin Luther King? I tried the advanced search and quotes but no success.
Thanks, Mark

I think you can search both the west and east German listings. I have at least one Martin Luther coin in my collection..

Hm, I just typed in Luther in the search bar, and after scrolling through the first 19 coins, which show Martin Luther King or or mention him in the description, I get a whole bunch of coins with a relation to the Luther you are looking for.

Click here to see the search.

I found out this is how to exclude terms in a Google search:
Martin Luther -King
Returns only sites with the words Martin Luther and not King.
Doesn't work that way on Numista but just FYI

You might find some more with other search terms, for example "Reformation"

https://en.numista.com/catalogue/index.php?mode=simplifie&p=1&l=&r=reformation&e=&d=&ca=3&no=&i=&v=&m=&a=&t=&dg=&w=&u=&f=&g=&c=&tb=y&tc=y&tn=y&tp=y&tt=y&te=y&cat=y

There are many commemoratiive coins and medals but seems we do not have that many here on Numista

Thanks!
