I am a huge fan of natural aussie Gold Nuggets. They are heaps of fun to have and to hold.
Each one is unique in size, shape and color, and unlike coins you can play with them with your sweaty hands to your hearts content. I have collected around 30 silver coins but get a lot more fun out of my couple of ounces of small nuggets that I am lucky enough to own.
I am biased because I can get out and find my own nuggets. They are mainly less than half a gram in size but very low maintenence to store and stash. The cotton gloves and never touch approach needed to play with or weigh a coin (gold or silver) makes me feel dissassociated from my treasures but holding and examining my 400 little nuggets is brilliant fun.
