A few quick factoids about the 1936 Cleveland Centennial Half Dollar...
Tidbit #1The coin's designs were reported as "completed" and "approved" in June 1936. The designs are the work of New York-based Artist/Sculptor Brenda Putnam.

Tidbit #3In June 1936, Thomas Melish reported that in addition to the face value of the first batch of 25,000 coins ($12,500), the Cleveland Commemorative Coin Association had additional coin-related expenses of approximately $4,500 - resulting in a $17.000 total cost.
The $1.50 per coin issue price produced top-line proceeds of $37,500. Thus, the Association yielded approximately $20,500 in bottom-line profits on the first 25,000 coins.
Melish reported that he expected a better net profit margin on the second batch of 25,000 coins as the Association would not have the startup costs to cover (e.g., Artist/Sculptor fees, US Mint die charges, lobbying trips to Congress).
Note: Melish claimed to have financed the upfront costs out of his own pocket.Tidbit #4The coins were available at the Great Lakes Exposition for $1.50 per coin, or via mail order for $1.65 (the additional $0.15 going to cover postage, insurance and packaging). Coins at the Exposition were sold in small, custom-printed envelopes.
