Numismatics, until recently a hobby of schoolkids, might just have got reinvented as an alternative insurance avenue designed to weather any economic crisis. Huge sums of money exchange hands through absentee bidders who travel across the world collecting vintage coins at international auction houses like Baldwin's and Spink. And, akin to portfolio managers who ensure best returns from stocks and bonds, there are numismatic advisors in the city who evaluate coins, keep track of their international rates and even provide advice on when and where the coins should be bought and sold.
