Rare Coins Guide

What is confirmed

Rare coins are a collection system. Some piggies can drop a rare coin instead of regular currency, and the collection carries across runs. The Luck branch is described as making rare piggies appear more often.

Those three statements are useful. They do not establish a fixed drop rate, a guaranteed target order or a profit ranking for every piggy.

Keep the collection goal separate from the bill goal

A rare-coin chase can pull attention away from current bill pressure. Before committing scarce cash or stamina to a collection attempt:

1. read the active bill and due window;
2. decide how much cash must stay reserved;
3. identify whether the target is a named piggy with a verified behavior;
4. treat the outcome as random unless the game explicitly guarantees it.

The Piggy Types Database can identify the five officially described types. The Bill Planner makes the reserve tradeoff visible.

Measure without inventing odds

If you want to learn from your own sessions, record attempts, rare-coin finds and the conditions you care about across multiple runs. That creates a personal observation log; it still does not prove a global drop rate. A small sample is a prompt for another test, not a universal table.

The visible Coin Collector achievement asks for the full coin collection. Track it in the 27 Achievement Checklist.
