The dime sized coin like object is a lead bale seal, similar to the one I found last year. Lead bale seals were used to label bundles of twine or wool or sacks of wheat, etc... The initials of the maker would be stamped on one side and the length, weight, number, etc... on the other. I think the MC stands for Maine Central, as in Maine Central Railroad.
The little twisted thing is a copper butter knife. There is also a small bell, about two inches tall, that probably hung from a goat's neck or a sleigh. (Are you listening?) And lastly, some silver, in the form of a "925" (indicating the highest quality Sterling silver) stamped earring.
It just makes me want to move to Florida for the Winter.
