This 2-coin lot includes both 1942 British Palestine 10 Mils metal variants struck in London under the British Mandate: one copper-nickel example and one bronze example. Standard references separate them as KM#4 for the copper-nickel issue and KM#4a for the wartime bronze issue. Numista notes that bronze replaced copper-nickel in 1942–1943 to conserve nickel for the war effort.  The copper-nickel coin has a documented mintage of 600,000, and the bronze coin has a documented mintage of 1,000,000. Both types share the same basic format: 6.5 g, 27 mm, plain edge, round shape with center hole, and medal alignment.  • KM#/Pick#: KM#4 (copper-nickel) and KM#4a (bronze) • Country/Period: British Palestine — British Mandate (1927–1948) • Ruler: George VI • Denomination: 10 Mils • Year/Date: 1942 • Mint: London, United Kingdom • Composition: Copper-Nickel (KM#4) and Bronze (KM#4a)  • Weight: 6.5 g each  • Diameter: 27 mm each  • Thickness: Bronze 1.7 mm reported in secondary catalog sources; copper-nickel thickness not fully confirmed in the sources used.  • Edge: Smooth / plain  • Shape: Round with a hole  • Alignment: Medal (0°)  • Mintage/Print run: Copper-Nickel 600,000; Bronze 1,000,000.
