Assume palm trees are 15 feet tall, dimensions of statue formed into a solid shape are approximately 30 ft x 40 ft x 50 ft, so a volume of 60000 ft^3

50000 tons of platinum has a volume of 75927 ft^3 (density is .6583 ton / ft^3)

So, approximately 15927 tons of platinum were (theoretically) put towards the
scar remover, meaning in today's money it cost 802 Billion dollars.
