Ok, my final coins have been put on ebay.
German Gold - http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=280714962687&ssPageName=STRK:MESELX:IT
Purple Haze - http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=280714965217&ssPageName=STRK:MESELX:IT
....... and my Green Giant. Research shows that this coin has the very first Green Giant tracking code from the 1st minting, so it could quite possibly be the first Green Giant released - http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=280714967866&ssPageName=STRK:MESELX:IT
God I'll miss them! Happy bidding!
