I’m making a currency for my world and I need some tips
I mostly want to know what would be best way to make them hard to copy, I was thinking something like a government symbol or a hidden marking that shop owners can see with some sort of device?
I’m not really sure, so if anyone has any ideas I’d love to hear them
A lot of currencies these days will have anti-counterfeit measures in place, and researching some might be a good place to start.
Off the top of my head, I know that here in Canada our bills have these kind of metallic strips and if you tilt them you'll see a portrait of whoever is on the bill. There's also something about the transparent strip on our money, which not only looks very cool but also has the number value written on it. It's not always immediately visible so it's usually a good indicator of whether or not a bill is legitimate or not, and it's also apparently really hard to accurately duplicate.
Another one that's a little more simplistic is having something really tiny, that might come up blurry on a counterfeit bill. Or having something written in raised ink.
I don't know if any of that is really what you're looking for but, I'd still recommend looking into how to tell the difference between legitimate and counterfeit money.
I do like those, here in Australia we are remaking all our notes to have a clear plastic strip in the middle of them with holographic designs inside.
I probably should have specified that all of my worlds currency are flat coins in the shapes of gem cuts. I’m currently deciding whether to make them out of different gemstones that have been cut flat or metal with tiny gemstones embedded in them, either way I wanna include gemstones somehow.
I’m not sure how one would make them hard to counterfeit, I was thinking something like a tiny holographic picture in the gem. I’ve tried to find info on what people do to stop coins from being counterfeited but all it came up with was how to tell the difference and not what they do to prevent it
