vintage

Hello All, I have been watching this site for a while as a guest but never posted, sold or purchased on here. I am a keen collector of Perth Mint, Geomin, older ABC as well as most Aussie silver vintage bars 1kg or smaller. Attached are some images of bars in my collection. Paying better...

Hi stackers, Saw this bar for sale for $900 and wondering if its a good deal or not. I know Harrington Metallurgist LTD doesn't exist anymore and would therefore attract a premium, but I can't seem to find any more info re mintage and availability. Any help would be appreciated!
