My thinking was more mundane; gold foam with a solid shell. But yeah, seems like there’s a lot of possible sources of error in the size/weight of a Galleon magic or no. Still, given the volatility of the Muggle marketplace and the isolation of the wizarding world in general, it seems likely that some arbitrage opportunities exist.
Not that I should care about the destruction of a fictional economy, but I much prefer the idea that arbitrage is only, say, 10%, and Harry decides to strike a long term business relationship with the goblins rather than taking an adversarial position and crashing the market in a big way. He could even introduce the idea of representational currency, which ought to be worth quite a bit to the goblins.

Given what I’ve seen about goblins up to now, I’d rather expect their reaction to be somewhere between “ROTFLMAO” and “Blasphemy!!!1!!”
