Casting tin soldiers is a classic hobby of the past, not much in vogue right now. I got a set of old molds on eBay, and interestingly the instructions say that pure tin is the ideal metal to use, resulting in clean, detailed, and bendable figures. But, they say, pure tin is much too expensive to use, so they have a lot of information about how to deal with tin/lead and other cheaper alloys. Tin is more expensive than lead, but unless you're planning to cast a heck of a lot of soldiers, it's not that expensive. Giving current thinking on the toxicity of lead, it's probably a price worth paying.
