A few that I remember:

A sister of the Liberty Bell cast by the same company and at the same time as the original (without the crack though)

The first copy made from the original Declaration of Independence

A blood-soaked timber support from a surgeon's table at the battle of Valley Forge

A desk used by Abraham Lincoln

Dwight Eisenhower's battle helmet (with 5 stars) from WW II

Babe Ruth's suitcase

A Honus Wagner baseball card

A letter from Ronald Reagan asking his daughter Patty to contact him (she never did)

[Errant]

Don’t forget one of eight remaining Bibles printed by the US Congress after we won our Independence.
