Denier Bracteate guziczkowy - unknown Prince Płock ND

One interesting fact about this coin is that it was minted during a time of great political and economic change in Poland. The Duchy of Masovia, where the coin was minted, was a powerful and influential state in the region, and the coin's design and production reflect the cultural and artistic influences of the time. Additionally, the use of silver in the coin's production indicates that it was a valuable and highly sought-after material in the region, and the coin's small weight of 0.21g suggests that it was likely used for everyday transactions and commerce.
