Griswold Cast Iron Comal or Griddle Bottom

This image features the underside of a cast iron cookware item, specifically identified as a Griswold piece by the iconic 'Small Logo' circular trademark. The logo consists of a cross centered within a double circle, with the name 'GRISWOLD' positioned horizontally across the center and 'ERIE PA., U.S.A.' curved around the inner perimeter. Below the main logo, the text 'MADE IN U.S.A.' is discernible, alongside a pattern number typically found on such pieces. The surface displays a distinct 'pebbled' or textured gray finish, characteristic of sand-cast iron. This heavy-duty metal construction shows signs of aging through patches of orange-brown surface rust and light carbon buildup, primarily visible near the bottom of the logo circle. The concentric circular ridges indicate a turned or machined bottom typical of high-quality mid-century American cookware. Based on the trademark style, this piece likely dates from the 1940s to the 1950s. The craftsmanship is evidenced by the clear, though slightly worn, casting of the trademark and the precision of the grounding rings, which were designed to provide flat contact on stove burners. Despite the light surface oxidation, the structural integrity appears sound with no visible cracks or warping in this view.

I have carefully examined the provided images of this cast iron cookware. The piece is a genuine Griswold 'Small Logo' griddle, dating from the late 1930s to the 1950s. The markings clearly denote 'GRISWOLD' and 'ERIE PA., U.S.A.' within the trademark cross, alongside the 'MADE IN U.S.A.' stamp. While the text is legible, the casting shows some wear consistent with age and use. The surface exhibits a textured finish with light carbon buildup and visible surface oxidation (rust), though the structural integrity appears sound with no apparent cracks. Market demand for Griswold remains consistently high among both collectors and 'user' enthusiasts. However, 'Small Logo' pieces are much more common than the earlier 'Large Block Logo' versions. The current condition is 'unrestored,' meaning the value is tempered by the labor required to remove the oxidation and season the iron. Comparable sales for cleaned versions of this griddle range from $85 to $110, while as-found examples typically settle in the $45 to $65 range. The primary value drivers for this piece are the brand prestige and the flat-machined bottom, which makes it suitable for modern range tops. A definitive authentication is limited by the digital format. In-person examination is required to check for 'spin' (warping) or thinning of the metal from excessive cleaning. I would also need to verify the absence of 'heat damage' (scale), which can permanently weaken the iron's structure and affect its ability to hold a seasoning. No scientific testing is required for this class of collectible, but a physical flatness test on a granite strike block would be necessary for a full valuation.
