Hi Judy,

Thank you for contacting Mearto with your appraisal inquiry.

The Delaware Statehood 200th Anniversary 23K gold stamp is a modern commemorative collectible, not an official postage issue despite its stamp-like appearance. These are not issued by the U.S. Postal Service and were never valid for postage. They were marketed as collectibles—often in subscription sets—during the late 20th century.

They tend to have limited secondary-market demand and value is generally tied more to novelty and gold content than rarity. Typical resale prices are often modest (frequently under $10–$30, depending on presentation and buyer interest). At auction, this commemorative stamp has sold for prices between $8 and $18.

Please let us know if you have additional items to appraise, or questions/concerns, and thank you again for using Mearto.
