¼ Tanka - Anonymous Gwalior ND

One interesting fact about this coin is that it was made of Billon, which is an alloy of silver and other metals, typically copper or bronze. The use of Billon in coinage was common in medieval India, particularly during the Delhi Sultanate period, as it was a more affordable alternative to pure silver. The fact that this coin was made of Billon suggests that it was likely used for everyday transactions and was accessible to a wider range of people, as opposed to coins made of pure silver or gold, which were typically reserved for larger transactions or ceremonial purposes.
