Patina

From Wikipedia: "Patina is a coating of various chemical compounds such as oxides or carbonates formed on the surface of metal during exposure to weathering." The silver dimes in my Roosevelt dime collection grew wonderful patinas from the cheap book they were being kept in for 20 years. Whereas patina used to be a numismatic curse, now it is an attribute widely sought. Anyone can find a brilliant uncirculated or proof version of a common coin; to have one with beautiful patina--now that's unique.
