Well, the EBAY auction is over and the Kangaroo went for $277.77. Just wanted to thank everyone again for helping me with the questions regarding the various cards for these coins. I appreciated your help.
I checked RAM's Annual Report, it was reported that there were 4,000 of the 2007 Silver Kangaroo minted but were sold in cases rather than cards. Is that why you say carded ones are 3rd party packaging? And the cards were added by dealers who requested RAM to mint them?
