Token Wien N.Ö.Landes-Irrenaanstalt - money of the mental hospital?

Also I found the same token with a face value "2":

What is it?, what years?, what equivalent of face value "1" and "2"?,..
Please, can someone tell something about these tokens?

Thanks,
Victor

Older then 1907 because it closed between 1903 and 1907. The denomination, I'd say Heller ... for Kronen it looks a bit small even for a token.

1864 - 1907
Look on page 578:

Hi, Peter!
In this catalog there are several hospitals with their tokens. All tokens are similar. It is obvious that denominations indicate the same equivalent. Do you think these tokens in Hellers?

Thanks!

Hi Victor,
Yes I think they are heller. There are a lot of notgeld notes. They have mostly 10, 20 and 50 heller. So I am sure. Coins are heller, too.
