How to Document an Antique Slot Machine's Age

Maker marks, model references, patents, catalogs, serial evidence and restoration history.

Antique coin machines combine historical artifacts, heavy mechanical assemblies, restoration choices and jurisdiction-specific law. The safest workflow is to identify, document, research legality, inventory completeness and only then decide whether to operate or restore the machine.

2. Serial numbers

Serial numbers should be evaluated against the exact maker, model, mechanism, age evidence, restoration history and intended non-gambling use. Photograph the machine before intervention, distinguish original parts from replacements and price freight before assuming a project is inexpensive.
