Hi Starting to feel like a bit of a free-loader, but i have a query on a couple more coins that were left to me. I have been left a 5 Yuan commemorative Marco Polo Chinese coin which i have been able to research as a mintage of 30,000, struck in 0.900 silver and weighing 15g. However i have also been left a 1994, Rembrandt commemorative 10 yuan coin of similar type and was wondering if anyone had information about silver content, & mintage numbers. Both coins are in capsules and are of excellent quality. I have also been left an Australian 1 dollar Kangaroo coin with Certificate Of Authenticity stating coin details (weight, size, silver content etc), but am struggling to find out mintage numbers as some put it as low as 15,000 and others as high as 73,000. I am also wondering if i am right in thinking that this was the 1st year the australia mint released these silver proof coins?? If anyonecan help, along with ANY idea of what i might get at a reputable dealer should i wish to sell that would be great. Still undecided about wether to hold on to them or not (advice again??) Thank you very much all for you time & assistance.. Richard
