To read a half hallmark on the bottom of a copper kettle, first, ensure good lighting and use a magnifying glass if needed. The hallmark typically includes a series of symbols or letters indicating the maker, purity, and origin. If it's partially obscured, focus on any visible parts of the symbols and consult reference materials or online databases specific to copper hallmarks for more context. If necessary, consider reaching out to an appraiser or antiques expert for assistance.

Since 1965 for dimes and quarters, and 1971 for half dollars, the metal composition is 91.67% copper with 8.33% nickel. Each outer layer is 75% copper/25% nickel, over a solid copper core.
Cutting a piece of copper in half is a physical change because it only alters the physical appearance of the copper without changing its chemical composition.
It is a physical change since...well...no other chemicals are involved...copper is still copper.
