AI Appraisal Estimate

This item is a vintage mid-century modern dinner plate produced by the Federal Glass Company. It is constructed from opaque white milk glass, a material popular for its durability and smooth texture during the 1950s and 60s. The plate features a distinctive graphic design known as the 'Kaffee Klatch' pattern, which consists of a central medallion printed in black and red. The central illustration depicts various coffee-service items, including a percolator pot, a creamer, a coffee cup on a saucer, and a decorative spoon or agitator. Encircling these icons is a red scalloped or rope-style border and the repeating German phrase 'Kaffee Klatsch.' The outer rim of the plate is finished with a wide, airbrushed black gradient edge (often referred to as 'atomic' or 'faded' trim). Physically, the plate appears to be in good used condition with the screen-printed graphics remaining vibrant and intact. There are no immediate signs of large chips or cracks visible in the photographs, though milk glass of this age often exhibits light surface scratching from utensil use. The bottom of the plate likely bears the Federal Glass 'F' in a shield trademark, common for this era of production. This highly collectible piece represents the Americana kitchenware style of the mid-20th century.

Upon direct visual examination of the provided images, I find this Federal Glass 'Kaffee Klatch' dinner plate to be a genuine representative of mid-century American kitchenware. The screen-printed graphics appear exceptionally vibrant, maintaining high contrast in the black and red pigments, which suggests minimal exposure to harsh automated dishwashing—a common cause of degradation in milk glass collections. The 'atomic' airbrushed rim shows consistent graduation without significant flaking, reinforcing a 'Good' to 'Very Good' vintage condition rating. The market for 1950s-60s milk glass remains stable, though specific patterns like Kaffee Klatch appeal to a niche segment of 'Coffeeana' and graphic-focused collectors rather than generalists. Comparables on secondary markets (eBay, Etsy, and specialized glassware auctions) typically see individual dinner plates selling between $20 and $40 depending on the intensity of the black fade. This pattern is less common than Federal’s 'Game Bird' or 'Zodiac' series, providing a localized scarcity that supports the upper end of the valuation. Factors impacting value include the absence of visible 'flea bites' on the rim and the clarity of the typography. However, this appraisal is limited by the digital format. A physical inspection is required to check for 'utensil marks' (silver-toned scratches) only visible under raking light and to confirm the presence of the 'F' shield heat mark on the base. For full authentication and to rule out contemporary reproductions, one would need to verify the weight, translucency, and tactile 'waxy' finish characteristic of authentic Federal milk glass. No scientific testing is required, but provenance regarding its storage environment would further solidify the premium side of the estimate.
