Vintage Lucite Coin Cube Paperweight with 1960s US Coins

This item is a mid-century decorative paperweight consisting of a solid, transparent Lucite (acrylic) cube with several United States coins suspended internally. The cube measures approximately 2.5 to 3 inches per side and features polished, sharp-edged geometry typical of 1960s and 1970s resin casting. Visible within the block is a 1964 Washington Quarter, notable for being the final year of 90% silver composition, along with a Jefferson Nickel (visible from the reverse showing Monticello), a Lincoln Penny, and a Roosevelt Dime. The coins appear to be in Uncirculated or Proof-like condition, suggesting they were encased shortly after minting. The Lucite remains mostly clear, showing minor surface scratches and internal reflections consistent with age. There is no visible yellowing of the plastic, which indicates high-quality resin was used. No maker's marks or signatures are present, which is common for these boutique desktop accessories often sold as executive gifts or souvenirs during the 1960s silver-to-clad transition period in US mintage.
