I'm a newbie to casting (I've been collecting some lead and making ingots, but haven't gotten any molds or a proper casting pot yet). I've been lurking about here and there looking at prices on molds and hoping to find one that I'm interested in, but have a question. I've seen several used molds (RCBS, Lyman) on ebay sell for just a bit less than the same mold would cost new...why? Is this a result of the buyers not realizing that they could buy a new one for about $15 or so more, or is there some benefit or desireable quality to the older molds? Like I said, I'm new to the forum and casting in general...I was just curious about this.
