The problem I've seen with the credits available from Disney and the copies online at Etsy and Ebay, is that the markings on them are invariably nonsense: for example, there's a New Republic coin that is supposedly a 500 credit coin, but the aurebesh tech numbers on them actually say 51 (a 5, then a dot, then another dot. Because they miss out the space that's supposed to be between the zeros, it turns the 00 into 1. This error is on the Disney originals, and it's made its way into all of the 3rd party copies.
There's the same problem with the 100 credit coin, which shows a value of 11 (again because they're missing the gaps between the zeros. Then there are the old Republic credit chips that just say "rowe" in aurebesh (presumably "Republic Owe': but they don't say how much they're worth. Again, the error is on the Disney originals and on all the copies.
The Disney New Republic 50 and 250 credit coins are (accidentally) correct because they don't have two zeros next to each other.
Then there are the long ingots, which make absolutely no sense. They have pseudo aurebesh tech symbols, but if you can read aurebesh tech, the numbers are gobbledegook. Again, the error is on the Disney originals and on all the copies.
The only really useful ones are the wupiupi coins available from hyperspace props on Etsy, which come in values of 4, 16 and 64 (equivalent to 2.5, 10, and 40 galactic credits), but we only know that because of the names of the coins and the values posted online. The only one of these that actually states its value on the coin is the copper 4 wupiupi coin (weirdly it's the only text written in aurebesh - it should be in Outer Rim Basic), and "wupiupi" is misspelled! And on the silver coin there's some text in Huttese Outer Rim Basic which misspells the huttese word "Lorda" (lord). Respect to Hyperspace Props for giving us these coins - admittedly they are nicer than the Disney props, but I hope they fix the spelling errors if they do another 3D print run. And it would be nice to have the values printed on all the coins.
No one - not even Disney - seems to get all their coin props 100% right, presumably because no one reads aurebesh, so they can't check to see check to see if the aurebesh or outer rim basic text makes sense. I wish I knew where these companies are getting their metal credits made - I'd do it myself (since I read aurebesh and Outer Rim Basic, I could get the text right). But I don't have a clue where to go to get them made.
By the way, if anyone is ever interested in making props that have the correct values on them, I'd be happy to help them get it right. I can read aurebesh, aurebesh tech, Outer Rim Basic, and Mandalorian.
