What did the medallions look like

[Lesser spren]

I'm re reading TBOM and trying to find a physical description of the translation and heat medallions, but I'm having a hard time finding it. does any one know where I can find it?

Chapter 12, when Hoid gives one to Wax:

Quote

The symbols on that coin … Wax thought, stepping back to the bar. They’re the same ones as on the walls in the pictures ReLuur took. He nearly overturned the wineglass of another guest in his haste to grab the coin back. He absently shoved the bartender another tip and held up the coin.
Those were the same symbols, or very similar. And it had a face on the back, that of a man looking straight outward, one eye pierced by a spike. The large coin was made of two different metals, an outside ring and an inner one.

chapter 21:

Quote

“Investiture,” Waxillium said. “This inner ring is nicrosil. You tap it, and it grants you Investiture—turning you into a temporary Feruchemist who has the ability to fill a metalmind with weight.” He held up the medallion. “The iron on this is for convenience, right? You can fill it, but so long as you’re tapping the Investiture, you could touch any source of iron and turn it into a metalmind.”

and the most specific, in Chapter 22:

Quote

Allik settled back, and Marasi—curious—picked up the Connection medallion that he had set down. She turned it over in her fingers, noting the sinuous lines down the center, dividing it into separate metals. Iron for weight, duralumin for Connection, and most importantly nicrosil, to give her the ability to tap metals in the first place.
She knew enough Metallic theory to identify the metals, but Connection … what did it actually do? And how did that make him speak a language of all things?

 

I hope this helps!
