People's Republic of Romania, 50 bani, 1955 Cupronickel, 4.5 g, 25 mm N# 9023

Xavier Rogé (Numista) @numista.com · 25/04/2025

Heavily worn coins have a charm of their own. I can only imagine how many years this one spent jingling in the pockets of Romanian workers.

Coins come in all kinds of shapes and techniques. Here are some bullet coins from Siam (Thailand): small silver bullets, bended into an almost ball shape and stamped. This kind of coins was used from the 13th century up until 1904.

Interesting discussion in the latest issue of the Bulletin of the French Numismatic Society: are the wreaths on the coins of the Achaean League olive or laurel leaves? The difference matters when describing coins accurately!

Many countries continue having bimetallic coins, so I guess it's worth it. I believe it's also a way to make counterfeits more difficult.

Silver turtles like this one were widely used in trade during the 6th and 5th centuries BC. The sea-turtle design is distinctive of the island of Aegina, located off the northeastern coast of the Peloponnese.

Ever wondered what a coin die really looks like? Here is a 15th-century lower die (on the left) and two upper dies (at the top) for hammering coins, and a 16th-century cylindrical die (on the right) for roller mills, seen at the Bode Museum, Berlin.

The numismatic world grows richer through its diversity and the interconnection of these groups. Recognizing and respecting each other’s interests will strengthen the entire community. 7/7

Xavier Rogé (Numista) @numista.com · 17/12/2024

I believe each group brings something valuable: knowledge, preservation, a strong market, an appreciation for history, cultural value, artistic beauty, shared learning, and new excitement. 6/7

Xavier Rogé (Numista) @numista.com · 17/12/2024

They forget that many serious collectors first discovered their passion through a simple circulating coin or a mint product that piqued their interest. Every collector has their own approach to the hobby, and there is no single "right" or "wrong" way to collect. 5/7

100

Xavier Rogé (Numista) @numista.com · 17/12/2024

Even among collectors, collectors of non-modern coins may dismiss those interested in modern non-circulating coins and other numismatic products ("pseudo coins"). Similarly, some collectors of beautiful rarities may belittle the occasional hobbyists keeping a few 2-Euro coins. 4/7

100

Xavier Rogé (Numista) @numista.com · 17/12/2024

Collectors often look down on investors, who focus purely on profit. Still they benefit from the dynamic coin market these investors support, rather than seeing their collection lose value over time. 3/7

100

Xavier Rogé (Numista) @numista.com · 17/12/2024

Academic and museum professionals sometimes dismiss private collectors, yet collectors have historically laid the foundations of many institutional collections and continue to enrich numismatic knowledge through their research and publications. 2/7

Xavier Rogé (Numista) @numista.com · 17/12/2024

I often observe tension between different sub-communities of coin enthusiasts, which I find unfortunate. 1/7
