Afghanistan has had nightmarish inflation for years, like 25,000 Afghanis to a dollar or something.
As Talibanic Islam is the most extreme harsh and primitive version possible, they probably consider money too wordly and consider Koranic verses as real wealth. I mean if Muhammad was born in 570AD, this extream Islam they practice is like 569AD.
They may also consider graven images of a mosque even too wordly and thus any money would just have writing on it. Pointless when only 40% of people can read and women are banned from any kind of learning besides shutting up and being household slaves.
I love coins. Especially silver, gold and anything really old.
