The design features the national star emblem at the center of a stylized copper-ore symbol, printed in bold red tones by the Casa de Moneda de Chile. In 1975, amid postal tariff changes, the stamp received a prominent “Revalorizada 1975 – 70c” red overprint, increasing its postal value from 40 centavos to 70 centavos. Revalued issues from this period are popular with specialists due to their clear economic and political significance and the variety of overprint types found in circulation.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp data-start=\"881\" data-end=\"952\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e \u003c\/p\u003e","brand":"Stamp and Cover Galaxy","offers":[{"title":"Default Title","offer_id":45847020306603,"sku":null,"price":20.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/2406\/6475\/files\/Scan_20251116_159__6.jpg?v=1763376542","url":"https:\/\/stampandcovergalaxy.com\/products\/scg9439-chile-1970-nationalization-of-copper-revalued-1975-40c-70c","provider":"Stamp and Cover Galaxy","version":"1.0","type":"link"}
