Don't know if many of these have come up for sale here in the last couple of years but for years before that these bars have been hard to get your hands on. I believe the mintage was 1000 and that a large number of them went into hiding in someones superannuation account. (Anybody who can confirm or deny or clarify please do.) Regardless they are one of the first and I think only 10oz bar made with 'Silver Stackers' and 'Silver Stackers.com' stamped on them which is only found on elsewhere on some 1kg poured bars and the XAG PENNYS and RAMS. NITTY GRITTY Auction ends Thursday Sept 22nd at 9.00pm. 5 minute anti-sniping times added to auction end until 5 clear minutes without a new highest bid. Winner to add $15 for express postage in Oz. Time to get a Stackable Stackers!
