AI Appraisal Estimate

This item is a clear, solid Lucite or acrylic resin paperweight in a cubic form, measuring approximately 2.5 to 3 inches per side. Embedded within the synthetic resin are several United States coins, most notably a 1964 Washington quarter. The 1964 date is significant as it represents the final year the US Mint produced circulating quarters with 90% silver content. The coins are suspended at various angles and depths within the cube, creating a three-dimensional visual effect. In addition to the quarter, other denominations such as a nickel and a penny are visible, implying a full set of 1964 coinage may be enclosed. The acrylic exhibits high clarity and sharp, beveled edges, characteristic of mid-century desk accessories. Regarding condition, the Lucite appears relatively clear, though there are minor surface scratches and fingerprints visible, which is common for this material. The coins themselves appear to be in Uncirculated or Proof-like condition with bright luster, protected from oxidation by the airtight resin seal. Notable is the absence of significant yellowing or 'silvering' (internal delamination), which often plagues older acrylic pieces. These items were popular souvenir and gift items produced during the 1960s and 1970s. The craftsmanship is professional, with the coins perfectly centered and free of air bubbles in the surrounding medium.

I have virtually examined this mid-century Lucite coin cube containing 1964 United States coinage. The primary value driver is the 1964 Washington Quarter, which contains 90% silver, along with the accompanying 1964 Roosevelt Dime (also 90% silver) and minor denominations. Based on visual inspection, the Lucite remains remarkably clear with minimal yellowing, a condition factor that significantly preserves its aesthetic appeal. The coins appear to be in Brilliant Uncirculated (BU) condition, retaining their original mint luster as they were encased before environmental oxidation could occur. This specific type of paperweight was a quintessential mid-century office accessory, peaking in popularity during the late 60s. Market demand for these items current fluctuates based on the 'spot' price of silver and the 'Mid-Century Modern' (MCM) decor market. Comparable sales for 2.5-inch to 3-inch cubes with clear resin generally fall within the $40 to $70 range. The value is capped by the fact that the coins cannot be graded individually by services like PCGS or NGC while encased. My assessment is limited by the inability to inspect for 'spidering' or deep internal cracks not visible in photos, and I cannot verify the exact silver weight without physical weighing. A full authentication would require an in-person examination under a jeweler's loupe to check for surface crazing and a high-intensity light test to ensure there are no hidden air bubbles or repair marks on the resin's surface. Documentation of the original manufacturer (such as the 'Kanawha' or 'Hillside' labels) would further solidify provenance.
