Ruling of Ancient Money Trading
Assalamu’alaikum. I’d like to ask about what is the ruling of ancient money/currency trading? For example, for IDR 1,- of the ancient money, the buyer should pay the price of IDR 15.000,-. Is it considered as usury? Since recently, there were many dowries that were paid using the nominal unit of rupiah, such as IDR 14,-. Please explain it to us, may Allah reward you with plenty of goodnesses.
