Let me know when you find one with those measurements, OK?
Best to report what you find to someone who can make an assessment. Or, take some electrical courses for 4 years so readings make better sense.
Do look out for hatchet marks on the outside of the coils. That's a bad sign.
Coil construction:
A wire with a thin insulation is wrapped many times around a steel core. (call it a primary winding)
Then another wire with thin insulation is wrapped many many more times around that first wrap. (call that a secondary).
Then the whole assembly is molded in plastic, after some wires are soldered to each of the internal wraps.
Copper doesn't deteriorate without exposure to acids or other corrosive materials.
The thin insulation on internal wires is protected by the plastic outer wrap.
If the outer plastic remains intact, the internals are protected.
If you pull out the small wires, you break internal connections. (999999999)
If you pull out the ignition leads, you break the internal connections. (9999999)
If you throw the coils in a fire, you might melt the internal wire insulation and the windings short out due to the copper wraps touching. (Zero, or near Zero)
What bizarre/contrived scenario can you expect the coils to alter their physical properties? Copper resistance doesn't change with time alone.
