Bidding for the 10 lucky number eights rare stamp we are auctioning for Operation Santa Claus unsurprisingly stalled yesterday after Wednesday's auspicious top bid of $88,888.88. The figure was a staggering 10 times our reserve price of $8,888.

But you still have five days to put in your own lucky bid for our unique Christmas gift - and give a huge boost to Operation Santa Claus.

The once-in-a-century 80 pfennig stamp was issued at 8am, on 8/8/1988 in Blindheim in Bavaria, Germany. The town's postal code is 8888. The first-day cover of the rare stamp issue has drawn huge interest in Hong Kong after being donated by Austrian resident here Erwin Hardy.
