Icon Request: Stack of coins

Please add a “stack of coins” icon to the Material Icons set.

It would be useful for representing payments, balance, rewards, and financial assets in apps and dashboards.

Optionally this can be just 1 coin.

Thank you.

Start by reviewing the existing Material Icons set and its contribution entry points, since the issue does not name a file or test. Add a coin or stack-of-coins icon that fits the set and verify that the new icon is available in the Material Icons collection.
