The Roman Dodecahedron - A Coin Gambling Game?

[RMwritings]

You place a coin inside, and roll.
If it falls out the bottom, you win.
The feet keeping it elevated, allowing your winnings to fall.
The bigger the coin, the more difficult the odds.
This falls in-line with why they are both undocumented and oft found in coin hoards.
Given their distribution, and assuming I'm even remotely correct, it would sound likely that for a period the gambling game was popular with Roman soldiers as they ventured.
They bare similar markings to other Roman dice, furthering the connection to gaming/gambling.
Everything points to a gambling device that you roll, doesn't it?

I hadn’t considered Roman dodecahedra in that way before your explanation is really insightful.

Science may have finally discovered an answer. It was Celtic...not Roman.
