Float them in a glass of water... the ones that sink are worth trying (and what else are you doing anyhow :-)?

Shannon, it's most probable that they're unfertilized (unless you've got lots of insects in your home, which is usually never good). If you want your bonsai to produce viable seeds, then you can try pollinating them with a painting brush.
