Recreating Currency of the Ages With a 3d Printed Stamp Kit and Multiple Designs.

I’ve always been fascinated by the history of ancient civilizations. One theme that consistently appears across different cultures and eras is the use of currency—both social and economic—in the form of coins and seals. These objects were not only tools of trade but also symbols of power, identity, and communication.

In this Instructable, I am hence focusing on the Middle ages and Renaissance.

Coins served as a prevalent means of transferring wealth—whether between individuals or larger groups—and were often used to convey the authority and influence of a ruler, dynasty, or state. Details such as the material used, the craftsmanship, the imagery or inscriptions, and even the techniques employed in their production could reflect the prosperity, cultural richness, or even the struggles of a particular kingdom.

This deep symbolism and historical significance inspired me to recreate coins and seals from various kingdoms of the ancient and medieval periods across the world. My goal is to help people of the 21st century experience a small, tangible piece of history. The first time I held a replica I made, it genuinely felt like I had been transported back in time.

This project is an open-source initiative aimed at creating a repository of clay-based coin and seal replicas, using modern tools like 3D printing to craft stamp holders and molds. Through this method, anyone can reproduce these historical artifacts in a hands-on, creative, and educational way—whether for learning, collecting, or simply appreciating the artistic and historical legacy of the past.

I have used the following equipment in making these coins and seals.

1. Fevi-Cryll ( Skin friendly and easy to use clay )
2. Acrylic Colors
3. Golden Color
4. Copper Color
5. Silver Color
6. 3D printed stamp holder
7. Stamp molds of different coins

I started with research of all the different coins and seals across the middle ages and more, after going through coins of different kingdoms and civilizations, I decided to re-create the following coins, This list is expandable and I invite all of you to add into the collection of these models with designs of your own.

1. Solidus Coin ( 312 CE – 10th century )
2. Gupta Empire Gold Coin (320 CE – 550 CE)
3. Pushyabhuti Dynasty Silver Coin ( 606 CE – 647 CE )
4. Dinar of Umayyad Caliphate (696 CE – 750 CE)
5. African Aksumite Gold Coin (270 CE – 600 CE)
6. Denier (Charles II) (840 CE – 877 CE)
7. Florentine Gold Coin (Florin) (1252 CE – 1533 CE)
8. Kaiyuan Tongbao Coin (621 CE – 907 CE)
9. African Sultani Gold Coin (1520 CE)
10. Akbar's Silver Coin (1556 CE – 1605 CE)
11. Chhatrapati Shivaji's Coin ( ~1674 CE – early 1700)
12. Spain Copper Coin (1812 CE – 1868 CE)

Then I started with the design of these models, for this, I have used the Fusion 360 Software and Blender softwares, you can use any CAD software of your choice. First I collected images of each coin, then converted those into SVG files using online converters. Then I imported the SVG files in Fusion 360 to sketch and extrude our designs.

Next I 3d Printed the stamps on my 3d printer and did some post processing to use the designs for making coins.

I have also designed this stamp holder and replacement mechanism to easily replace different molds and easy coin making.

Then I processed the clay to shape and mould on the coins.

I used the stamp holder to print on the clay using different molds.

Then I painted all the coins using acrylic colors

I further added details for giving an oldish look to the coins

Finally here are the coins. Perfect for a collection of yours.
