Good article in today's SMH about the Holey Dollar, and an upcoming exhibition in Sydney. If I read the article correctly, the exhibition includes 13 of the most significant holey dollars, with a total estimated value of $7.3 million The Macquarie Group Exhibition of Holey Dollars starts on October 2 at 1 Martin Place, Sydney. The exhibition is open to the public and admission is free. http://www.smh.com.au/money/holey-sound-decisions-20130924-2ub1g.html
