New York Yankees

1909–1912
The Highlanders' original "NY" logo was based on a medal of valor that was designed by Tiffany & Co. and presented in 1877 to John McDowell, a New York City police officer shot in the line of duty. When the team changed their name to the Yankees in 1913, they would continue to use this symbol as part of their identity, albeit with minor changes over the years.

1968–present
In 1968, the top hat had its design adjusted, with the underside being made white.
