What are pearls on an Israel coin ?

I have a 1949 Israel 25 Pruta coin. The catalogs shows two types. One with "pearls" and one without "pearls". I have looked at pictures of this coin on the Web, both with and without "pearls", and can see no difference in the coins. What are "pearls" and where would they be on the coin?

Thanks for the help.

   Welcome to the site.  

A Numista member called cobra owns that site in the link, and it has lots of good coin varieties on it - with pictures, including yours. It is a tiny dot below the  ▬  at the base of the wreath.

I have these Israeli prutah coins, both with pearls and without.   You're looking for a very small raised dot on the lower part of the reverse. They are very tiny!

Glad someone knew where to look and what the pearl was. Had to look real hard to see mine did not have a pearl.

Thanks for the help
