I am not an errors collector. Occasionally some of these confound me and this falls squarely into that category........ This was in my Great Collections email today. An Ike partially struck on a Taiwanese one dollar planchet. Does the mint strike coinage for Taiwan or is this confirmation that funny business takes place at the US mint?
Yes, the US Mint did strike coins for other countries, until 1984. https://www.pcgs.com/news/will-us-mint-once-again-produce-coins-for-other-countries Quoting the PCGS article, the US Mint "has struck coins for Argentina, Australia, Bahamas, Belgian Congo, Belgium, Bolivia, Brazil, Canada, China, Colombia, Costa Rica, Cuba, Curacao, Dominican Republic, Ecuador, Ethiopia, Fiji, France, French Indo-China, Greenland, Guatemala, Hawaii, Honduras, Israel, Liberia, Mexico, Nepal, Netherlands, Netherlands East Indies, Nicaragua, Panama, Peru, Philippines, Poland, El Salvador, Saudi Arabia, South Korea, Surinam, Syria, Taiwan, Thailand and Venezuela."
Taiwan $1 coins were struck at the Denver mint in 1973 and 1974. I bookmarked this link to the mint error news years ago. Click the link to the spreadsheet. It has the dates, compositions, weights, sizes, mintages and mint used. This really helps when the "struck on foreign planchet" question pop up here https://minterrornews.com/news-5-13-03-foreigners_in_the_mint.html
There is a book you can usually pick up cheaply: Domestic and Foreign Coins Manufactured by Mints of the United States 1792 -1965. That's probably where the info above came from.
