Request for future Marblehugger owners

Just a tiny request for everyone who at some point will own one of my Marblehugger dragons. This is completely optional, and you're not required to do this if you can't/don't want to do it or just plain don't feel like it, but I thought it would be cool, so...

If possible, could you take a photo of your Marblehugger with a coin of your country's money?

I was asked how big they are, and realized that I don't have any size reference photos of them. Usually when people take such pictures of small things like these, they put them next to a coin, but I have always found it a bit troublesome, since the coin sizes vary from country to country, and I have no idea of what size exactly are stuff like US dollars (or really anything other than euros). So I thought it would be fun to have a collection of photos with different kinds of coins from all over the world.

And besides, dragons are treasure hoarders, I'm sure they'd love to be next to money.
