Stacking silver and gold doesn't always have to be boring. Although we might be better off financially investing in only eagles it is fun to also have a few pet coin collections to indulge in each year. My favorite silver coins to collect are the silver panda's, Perth mint lunars, kookaburras, and koalas. With the gold price rising I have limited my gold collection to just the gold 1/10 ounce lunar series and 1/10 ounce Australian kangaroo coins. These series give me plenty of variety in my collection and are quite beautiful to get out every now and then.
