I love old signs and that’s a cool early example of aluminium, so we can forgive its battered appearance.
Since aluminium is rarely found as a native metal and the process for extracting it from bauxite even in tiny amounts wasn’t developed until about 1825, it was originally regarded as a precious metal. Even by 1852 it still cost $34 an ounce versus gold at $19 an ounce. Further industrial innovations progressively took the price down to about 4 cents an ounce by 1889 and then it really took off for commercial manufacturing of everyday items.
The New Jersey Aluminum Company was founded in Newark in 1890 and was one of three companies that merged to become the Aluminum Goods Manufacturing Company in 1909 (and relocated to the Midwest), so that’s the timeframe for your sign.
Note that my English spell-checker turns its nose up at ‘aluminum’. To avoid any dispute about correctness, how about… just call me Al.
