Class, Series and Collections: How to Judge an NFT Safe's Rarity
Every NFTAMA safe has a class, a series and a design — its picture. This is not only about collecting: the class sets the weight multiplier and what the safe can do, and different designs of one series give a collection bonus to weight in the reward distribution.
Classes and series
| Class | Series | Chance | Weight multiplier | Designs | Level cap |
|---|---|---|---|---|---|
| Regular | Regular | ≈87% | ×1 | 53 | 10 |
| Silver | Goods | ≈8.7% | ×1.1–1.3 | 9 | 15 |
| Gold | Moon | ≈4.3% | ×2–3 | 9 | 20 |
Base chances for a showcase purchase. The account level adds up to +13 pp to Silver/Gold, and in the forge the odds depend on luck and the parents' genes.
The class is rolled when a safe is bought on the showcase or forged. Besides the multiplier, every safe has a quality — its exact multiplier within the class range. It decides how much each level adds.
The collection bonus
If you hold different designs of one series, every safe of that series gets extra weight in the reward distribution — a share of its base weight:
| Different designs of a series | Bonus |
|---|---|
| 3 | +2% |
| 5 | +4% |
| 10 | +7% (the Regular series only) |
Example: a safe with a 50 AM base weight counts 3.5 AM heavier in the distribution at +7%, however many levels it has. The bonus never lifts the weight above capacity, and the safe's own weight and its “+xx%” do not change. The card shows the bonus next to the series name, e.g. “Regular +7%”.
How to judge rarity when buying
- The class matters most: each Gold level is 2–3 times stronger and the level cap is 20.
- A design new to your collection can be worth more than usual: it raises the bonus of the whole series.
- Traits: growth, capacity, rarity gene and mint resource. The lighter a safe was born within its range, the better they are.
