Sadly those one dollars are not worth much, and only worth something to a collector of Non-circulating coins, since usually they are bought at retail price $5+ for a for a 1 dollar phar lap coin. So it would depend on buyer maybe you can get full retail but the market is very small for these items. for the high value coins sell them individually unless you can find a buyer who want all of them in one go, but for the lower value items it depends on how fast you want to sell them.
Olympic set from memory are about BV+50%, so dont quote me on that.
DONT SELL TO PAWN SHOP as they either willn't buy or do not care about the value you place on them they will probably offer FV (face value) + 20% to 100%. Remember
ebay place a fee on your sales of roughly 10% plus there is a paypal fee of about 2.5%.
As for the 1kg
Kookaburra 1992 in pristine condition usually BV (700ish) (melt value/base value)+ 100% since the earlier ones are quite rare, but again it depends on the buyer as the market for these items is small. Also only the later
Perth Mint items have lost value due first in part because of high retail prices, base value of silver and gold and last due to high mintage numbers. However your
Kookaburra have risen in value if your father in law did buy them in 1992 both in retail and base value.
