AI Appraisal Estimate

This lot contains two Mk 2 defensive fragmentation hand grenades, commonly known as pineapple grenades. The cast iron bodies feature the iconic segmented pineapple pattern designed to enhance fragmentation upon detonation. Both specimens appear to be inert or deactivated training versions or military surplus collectibles. The cast iron shells exhibit a dark, oxidized patina with significant surface rust and pitting, particularly visible in the deep grooves. One grenade (right) possesses a partial fuse assembly including a green-painted safety lever (spoon) and a metal pull ring, though the striker mechanism appears inactive. The other (left) is missing various fuse components. These items likely date from the mid-20th century, specifically the World War II to Korean War era. There are visible numbering marks stamped into the cast iron bodies, though they are partially obscured by corrosion. The overall condition reflects heavy age-related wear, with significant surface degradation that is typical for surplus metallic militaria of this vintage.

I have conducted a visual examination of this pair of Mk 2 'pineapple' hand grenades. Based on the casting patterns, standard serrations, and the presence of surviving green paint on the safety lever (spoon) of the right-hand specimen, I have identified these as authentic mid-20th-century ordnance, likely dating to the WWII or Korean War eras. The condition is fair to poor, characterized by significant oxidation and heavy pitting across the cast iron bodies. While the right grenade retains its external fuse assembly and pull ring, the left unit is missing these components entirely. Market demand for Mk 2 grenades remains steady among militaria collectors, though value is heavily dictated by 'completeness' and the presence of original finish (OD paint/yellow bands). These examples lack original paint and show advanced corrosion, which limits their appeal to entry-level collectors or those seeking 'relic' condition items. Comparable sales for single incomplete relic Mk 2 bodies range from $40 to $75, while complete deactivated units with intact fuses and spoons command $125 to $175 each. Limitations: My assessment is based solely on high-resolution imagery. Visual inspection cannot confirm the internal inert status of the items; I must assume they have been professionally deactivated as per safety standards. A physical examination is required to verify the integrity of the threads and determine if the fuse assemblies are original to these specific bodies or later replacements. Furthermore, scientific metal analysis would be necessary to distinguish between genuine military-issue cast iron and high-quality post-war commercial reproductions, although the level of pitting observed here strongly suggests authentic age.
