Object: 1976 Eisenhower silver dollar
Packaging: small plastic flip
Note: none
Delivery: 2058-06-15, Adams cabin, Arley AL
Recipient: Barrett's son
Postmark: Olympus Mons

Reason the date matters:

1976 is Josh Adams's birth year. The coin is not valuable in the ordinary
numismatic sense. Its value is that it is legible to the household without
requiring explanation.

Handling:

The boy asks his grandfather what year it is. Josh says the year of his own
birth without looking up from page 142 of A Pattern Language.

Ledger class:

Small-object kindness. No request. No reply channel. No attribution burden.
