Yes! There are some varying ways to produce coins. The cheapest ones come from China, usually cast in zinc and plated. Higher quality coins are made in solid metals and are struck on presses kind of like ours but their processes are usually more modern and streamlined. Our higher costs come from: licensing (part of your purchase goes to Brandon), engraving (done by hand by Woody, our super talented engraver), metal (sourced in small batches in the US), minting (on one of our antique presses 1700's-1920's era machines), finishing (darkened and aged to feel perfect), packaging (high quality archival holders with printed card insert), and of course labor. We've got a LOT more flexibility in the coins but it means that our costs are higher than probably any other mint. This is a really subtle thing, but as far as I know, we're the only mint broadstriking our coins. This means the coin isn't fitted into a collar which would give it the sides on the edge like all modern coins. So our Era 1 coins are broadstruck on one of our older presses with smoother, rounded edges where the metal bubbled out when being pressed and the Era 2 coins are collared in our new modern press (from the Denver mint!) and have those sharper sides plus an intermittent knurled edge which we've never done before! You should be able to see those differences in the photo. All of these elements are again super subtle but important to us since we can create these coins exactly how they should be.
tl;dr: making coins the old way is more expensive but dang they look good.
