Certified by Karl Stephens sold to my parents probably in 1980. 

***NOTE: Listing has been revised after research into the grading scale used by Karl Stephens.*** 

RE his certification rubric - copy includes mispellings:  

"We have received questions from time to time about our grading of uncirculated coins.  Wile we don’t use MS numbers in our lists as a rule, we do have a  verbal description that corresponds to each number.  Fortunately, the price ratio versus MS# on foreign coins is miniscule.  For clarity, and for comparing on coin with another, we do feel as accurate a description as possible is desirable."

Description on the package says:

1972 25 Schilling

CH PF

Austria

Y-128

Ziehrer

I

From Numista: 

100th Anniversary of birth of Max Reinhardt

* According to Karl Stephens website, Choice Proof translates to an MS number of 65. Link is here: https://karlstephensinc.com/grading-notes/

Coin has been kept in a safe deposit box for 40 years. 

Note, I am not a coin person. I am selling these from a private family collection. Yes, I will combine shipping as coins are wee. :)
