Here's another Index to a set of posts I've made about classic era US commemorative coins that fit the topic or theme of "Coins with Industrial Imagery" over in the "Post Your..." forum area:
Post Your... Gallery topics.
Though none of the US commemorative coins of the classic era directly present an industrial scene (e.g., depict a factory), several do feature design elements that are symbolic/representative of industry - these are the coins included here.
1.
1893 Isabella Quarter2.
1920 Maine Statehood Centennial3.
1934 Province of Maryland Tercentenary4.
1936 Cleveland, OH Centennial / Gret Lakes Exposition5.
1936 Wisconsin Territorial CentennialI made a conscious decision to not include the 1925 California Statehood Jubilee and the 1935-36 California-Pacific International Exposition half dollars even though their depiction of an individual engaged in gold mining might be interpeted by some to be reflective of California's gold mining industry. The reasoning behind my decision is based on the fact that each coin, based on the gold mining activity depicted, presents an individual effort vs. that of a larger scale commercial operation. I believe that to truly be "industrial imagery," an included design element needs to reflect a larger-scale, coordinated effort vs. individual activity.
As I've stated in my previous Index posts, there is quite a nice array of world coins on display in the target thread - this time with a variety of industrial themes - so scrolling around a bit after you check out one or more of my classic US commemorative coin posts is highly encouraged - you might find a new collecting interest!
