I've been into smaller investments lately myself, though not gold specifically—more like digital stuff, where I can buy and sell quickly. If you’re looking for something with lower upfronts, trading digital items might be interesting, too. For example, if you’re into gaming, you could
buy cheap CS skins and see some returns there. It’s obviously different from physical gold but can be a way to diversify small investments without all the fees and taxes that sometimes come with precious metals.
