Iran 1 rial 1338-1356 wrong date distribution

In the article https://en.numista.com/catalogue/pieces6326.html
It is stated that
The list of years is complete and has been verified.

Though this statement is at least strange, for the list is completely wrong!
The last year is given in the fantastic form:
1356 (1977) ۲۵۳۶ (="2536"; date variety)

There oblige to be
2536 (1977) ۲۵۳۶

It is obligatory, for the search in the site avoids the coin with this uncommon date at all!
