Upside Down Sun Yat-sen Stamps Worth a Fortune

I am currently busy going through a shoe box of old China stamps I have after reading the news that some rare Sun Yat-sen stamps sold at auction for US$707,000 in Hong Kong – a world record. Seems the good Dr’s face is printed upside down making them extremely rare and getting them more than double what any SYS stamp has ever sold for before. More about it all here.
