Why does a 1 oz silver American eagle coin appear larger than a 1 oz gold American eagle?

Is the gold a more dense metal? Or is is simply an optical illusion and the thickness is actually greater on the gold coin?

It is not an optical illusion. Gold is the denser metal, as you correctly suspect. Therefore, when comparing coins of the same weight of gold and silver, the gold coin will be the smaller in size.

Besides, gold coins are just fascinating to collect!
