Ashley, Michigan - 48806. Ashley is located in eastern Gratiot County just a mile north of M-57. This village was organized in 1884, named after John M. Ashley, then owner of the Toledo, Saginaw and Muskegon Railroad. He built a spur to the town at that time - most likely for the transportation of lumber harvested in the area.
While silver is not toxic, repeat intake of small amounts of silver over time can result in argyria. In people with this condition, silver builds up in body tissue, giving it a gray-blue appearance when exposed to the sun. In addition, the ingestion of large amounts of silver can have negative effects on the body.
Silver has been used as a drawing tool for centuries. Pure silver leaves a light gray patina like a hard pencil on the paper. The light gray silverpoint values will darken with time as the silver tarnishes from gray to black. Gold will also leave a unique mark on paper but it does not tarnish like silver.
