Well silver density is 10.5 Kg/dm³. but rugby ball volume is quite difficult to calculate... I made an aproximation calculated as two opposite cones taking the max. size and it gave me a little more than 3 dm³, so the wheight would be about 31.5 Kg. Actually even more as the ends of the cones in the ball are rounder so they have a bigger volume...
