| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Currency (currency) | historical_predecessor | 72% | expert_inference | Standardized coinage is a concrete institutional form of classical currency rather than a separate hard engineering layer. |
|
| Gold and Silver Working (gold_and_silver_working) | required | 82% | textbook | The earliest attested coins used electrum, a natural gold-silver alloy, so precious-metal working is part of the scoped material capability. |
|
| Record Keeping (record_keeping) | historical_predecessor | 75% | expert_inference | Record Keeping is an earlier historical predecessor or foundation, not a one-to-one engineering dependency. |
