Count each coin once, in this order
- Non-U.S. coins: Coins identified as non-U.S., even if dated before 1960. Include them in the batch total.
- U.S. dates before 1960: U.S. coins with a clearly readable date earlier than 1960. This is a date observation, not a value or rarity claim.
- Other coins set aside: Other coins needing closer study, including unreadable dates. Exclude anything already counted above; this is not an authenticated error count.
