Have been cleaning out my drawers and found two silver coins I purchased from the Royal Australian Mint that I had forgotten about. There are: 1) 2003 silver $1 Korean War proof coin (99.9% fine silver, 11.66 grams, 25mm diameter, mintage of 15,000) 2) 2003 silver $1 Kangaroo (99.9% fine silver, one troy ounce, 40mm diameter, frosted uncirculated finish)
If someone walked into my office I would pay, 1) 2003 silver $1 Korean War proof coin $11 2) 2003 silver $1 Kangaroo $30 PD
PD, I think your prices are basically based upon the silver value of each coin, paying $1 a gram which is about spot price. In an open market you will also get collectors prepared to pay a numismatic premium on each coin.
I would pay $50 for the pair. Better still, list it on a sales tread at Silverstacker and get even more.
