Thank you for viewing. This is a commemorative medal set from the 20 pavilions of EXPO'70, held in Osaka in 1970. It seems to be a rare set due to the number of medals and the size of the frame. It's in a metal frame with glass and can be displayed standing up. A certificate seal is attached. Since it's old, I checked the back of the frame for the first time in 55 years before listing it. Some of the backs of the coins show signs of rust, but the visible sides are still in good condition. Would you like to add it to your collection? #EXPO'70 #OsakaExpo #CommemorativeCoins #20Pavilions
