There is nothing to avoid in 1990 against this $ 5 bill or $ 5 worth of gold, with $ 5 worth of gold by that time going to get a 2.60% investment profit now, this value will benefit greatly.
Everyone will be enthralled and totally obsessed with the Coca-Cola MagiCans treasure hunt in that period of time and I'm sure there must be people who still remember it, congratulations @goldmatters can find one of those cans.
Thanks
