About Us

Where Passion Meets Precision in Numismatics
Solo Numismatic was born from a single banknote and a deep appreciation for history. In 2010, our founder, Gustama, inherited an old Indonesian banknote from his mother. That moment sparked a lifelong passion and a new journey—combining the art of collecting with the precision of business.
With a background in metallurgy, Gustama’s expertise naturally expanded into precious metals trading, giving Solo Numismatic a unique edge in understanding both historical value and real-world market fundamentals.
