1935 S San Diego Pacific Expo Commemorative Half Dollar – Uncirculated. Thank you for viewing this listing. Shopping will be easier by using the Category links noted on each page. You will find hundreds of coins and numismatic books fairly-priced and I often have a store-wide sale. Each additional coin adds only 25 cents per coin. Please be aware of this when purchasing. As you will note from the feedback I have received, I carefully wrap all coins and books while using the best mailing materials. Thanks again for looking.
