The Circular Slide Rule geocoin is the personal geocoin of the Dutch geocacher technetium, who designed this geocoin together with Chuck Turner from Palehorse Design (PHDCoins.ca). They have made a functional geocoin, which can be used for math operations like multiply or divide as well as for sinus or cosine calculations.
For example: Align number 1 from the outer circle with the number 3 from the inner circle. The number 12 from the inner circle will now align with number 4 from the outer circle (12 is the product of 4 cross 3). The number 1.67 at the outer circle can also be regarded as number 16.67, number 166.67, etc. This will give you number 5, number 50, number 500 and so on. Because the numbers on the circular slide rule are alinged in a circle this will continue ad infinitum
The center of the geocoin contains a fractal (a Sierpiński's triangle), which describes an infinite repetition like the numbers on the circular slide rule. The largest triangle of the Sierpiński's triangle contains the electron configuration scheme of the chemical element technetium. Technetium is the element with the lowest atomic number in the periodic table that has no stable isotopes: every form of this element is radioactive. Therefore the other triangles are empty or shows x-rays of the decayed element.
Design
The coin has a diameter of 50 mm (2") and a thickness of 5 mm (1/5"). A small rotating disc is located in the middle of the geocoin. I.e. the geocoin is a functional circular slide rule and can be used for math operations like multiply or divide. Including a trigonometric scale, it can also be used for trigonometry calculation of sinus, cosine, etc. The tracing code is placed on the edge.
On the back of the geocoin a Smith chart is shown. The Smith chart, invented by Phillip H. Smith (1905–1987), is a graphical aid or nomogram designed for electrical and electronics engineers specializing in radio frequency (RF) engineering to assist in solving problems with transmission lines and matching circuits.
In total five finishings were minted:
- Technetium’s Slide Rule Geocoin (Polished Gold) - Morning in Gold Edition
- Technetium’s Slide Rule Geocoin (Antique Bronze) - Evening in Bronze Edition
- Technetium’s Slide Rule Geocoin (Polished Silver) - Night in Silver Edition
- Technetium’s Slide Rule Geocoin (Satin Gold/Satin Silver) - Special Edition
- Technetium’s Slide Rule Geocoin (Polished Nickel) - Artist Edition
Technetium’s Slide Rule Geocoin (Polished Gold) - Morning in Gold Edition
The Technetium’s Slide Rule Geocoin is one of the geocoins I have retrieved out of the JackHoe collection! I really appreciate the opportunity to get a part of his stunning dutch geocoin collection
The aim of this geocoin is to please everyone who looks at this beautiful geocoin and discovered it

Am 08.10 waren wir DVERK's und unser Sohn Liam (LErdO) zu Gast in Holland auf dem Event Saens Kessers Evenement [SAKE2016] - GC64Z75-. Wir hatten die weite Anreise auf uns genommen und haben nicht nur viele nette Menschen getroffen, sondern auch bekannte Gesichter gesehen. Es hat uns sehr gefreut dich mal wieder zu sehen und mit dir ein paar Worte wechseln aber natürlich und insbesondere deine fantastische Sammlung begutachtet. Daher bedanke ich mich dafür, deine besondere Sammlung (und deiner Freunde) discovern zu dürfen, es ist mir eine Ehre! Liebe Grüße aus Essen/NRW und wir sehen uns bestimmt in Maije oder in Bremerhaven wieder. Danke fürs zeigen! Tom

I have been given this incredibly huge collection of trackables by Geo-Dragonchild. Since that moment I am trying to visit (and admire) individually as many of these trackables as possible - but the collection is so big that I may not be able to visit all of them in details. I met Geo-Dragonchild perhaps several times during various Mega and Giga events in Europe, definitely it was this month at North Wales Mega event on the beautiful Llangollen canal. The Geo-Dragonchild's collection gives really a pleasure to browse through. I congratulate the owner for the given time and investment that this collection represents. Indeed, incredible! Thanks.

This guy introduced me to geocaching a day in October 2011. The days are still counting 😁! Now I was invited for a great evening with chat and "coinfest". I am really proud knowing you and what a great collection. The coins are amazing!
Thanks Geo-Dragonchild for everything! Hope to see you soon again.
