The primary trap that youâll find with aluminum cans is a higher than normal premium on the product. With a $0.60 per pound market rate for general aluminum, the least you should receive for your cans is $0.30 per pound. Anything less than that is a scrap yard dealer attempting to maximize their profits at your expense.
Lake Superior agate. The Lake Superior agate is a type of agate stained by iron and found on the shores of Lake Superior. Its wide distribution and iron-rich bands of color reflect the gemstone's geologic history in Minnesota, Wisconsin, and Michigan. In 1969 the Lake Superior agate was designated by the Minnesota Legislature as the official state gemstone.
Among my favorites are Little Girls Point and Black River Harbor in Michiganâs Upper Peninsula near the border with Wisconsin. Black River Harborâs beach is where I found my first agate (see picture) and Little Girlâs Point has I believe the largest variety of rocks and gemstones anywhere around Lake Superior. If you arenât lucky enough to find an agate at LGP, you will for sure find some attractive rocks for polishing.
