"Hmmm... I suppose paper money is fine for your world, but it wouldn't survive long enough to be a viable option in ours. Between the dragons, gryphons, and sea ponies..." It was still an interesting concept in her mind however.

Trixie would be the one to figure out how to counterfeit money, and then immediately find a way to prevent it... Keeping the knowledge of how to do it locked away forever and only releasing the ways to stop it... She's nothing if honest when it comes to things like that.

At the mention of coins costing more to make than their worth, she looks curious. "Isn't that the same as paper money? It's only worth is what one says it has... coins at least contain metal..." She honestly is confused, but she'd not object to a change in the subject either. This was getting to be too technical for a fun dinner out.
