Rudeboy...If a kid has the “good fortune” to catch a ball and then asks the hitter to sign it and is told that it will be $30 I would suggest the kid’s parents check their eBay app and if a ball signed by this player is going for more than $50 they should encourage the kid to pay up and go home a sell it on eBay for a profit. With that profit they should then encourage the kid to invest in silver.
Alternatively, if Jay ZX sells on Ebay for $30, the parents should encourage the kid to write Lego and get one for free, and then sell it . . . teaching the same lesson you provided.
