Iran 1 Rial 1977 MS 2536 KM 1171a clarification [solved]

Hello, was wondering, on the page for this piece, there are specified slots for varieties for this piece of large & small date coins. However there are no contrasting pictures of these varieties, & since I have only 1 piece I have no idea which category it should fall under. is it possible to add this clarification? The Krause Edition I have only mentions large/small date for 1974 SH1353 for this type, which is also not shown pictured on the page.

thanks

I have not been able to find pictures from an allowable source (and so I am unable to add pictures to the page that show the difference); however, this link shows the difference for 1974:

A comment has been added explaining the difference between those two.

So... what about 1977? Well, only one line exists now. It appear the large date variety is located on this page:

(The only difference between the two types seems to be the obverse legend, which is not that apparent at first, if you do not understand the language.)
