Aren't the "Western" numerals "Arabic" numerals?

The term "Arabic numerals" arose to distinguish them from the old "Roman Numerals" system widely used before their introduction. The numerals usually used in the West are more properly known as "Western Arabic" numerals. The numerals which actual Arabs use, in Arabia and elsewhere in the Middle East, are more properly known as "Eastern Arabic" numerals to differentiate them.

As to their derivation, they (or symbols very much like them) have indeed been used for millennia in India. When the Arabs conquered parts of India they brought the concept back West with them, and Europeans learned them from the Arabs. But their shapes and forms have evolved over time, and with geography. Some of those evolutions are simply errors in transcription: the shape of "Western" numbers 2, 3 and 7 are clearly evolved from writing the Eastern Arabic numerals for those numbers (٢‎, ٣‎ and ٧) sideways. Our "4" is also clearly derived from a sideways Persian "۴".

Back to the point of this item in question: the figure on the reverse (?) is the numeral "2"; this is written in "Western" style, rather than Arabic or Persian style. So if it is indeed from Iran (or elsewhere in the Middle East), then it was made for use by Westerners there.
