It has the frozen year of AH 1255 (1839), which is the ascension date of Ottoman sultan Abdulmecid I; the regnal year is 2, indicating 1840 as a date of issue.
Verweis : "ALLRED1950"Thank you Cass. Was looking in wrong country.
Tis' nothing.
Egypt was an Ottoman vassal from 1517 to 1914, so for centuries the coins they minted were quite similar to Ottoman issues, with the tughra and so on. It's very much a reasonable mistake to make.
Daryl's coin weighs only 0.67 g. Of course it has some worn, but not that much it lost half it's weight. So it's not the 20 para KM# 653 but the 10 para KM# 652 (https://en.numista.com/catalogue/pieces19335.html)
