Merchandise Suggestion: Coins

So I was looking at the PBE and Riot is giving us some new loot to get skins from with the next update. And looking at the Golden Kraken, I thought to myself that I would love to get such a coin irl. https://4.bp.blogspot.com/-Ez1Aes_HPjs/WvyPgW2cY5I/AAAAAAAA_vA/nyZii-C9NBQVWcTc6it3NIvzfGIksO6cgCLcBGAs/s1600/golden-kraken-490x490.png

I just love collectible coins and this design is awesome. Thinking about it, we already read about some currency from the lore in the past, for example Zaun (gold hexes). Or I could imagine them designing an Ionian coin, resembling ancient Asian currency.

Maybe Riot could design a coin for each region of the game and sell them seperatedly and as a collector's pack?
