hello! I've recently won this coin, but I doubt their authenticity.


im 99% sure that Ducat is fake, but I'm still doubt about ottoman Cedid Mahmudiye.

The Ottoman coin looks good to me. Here is an example that sold a while ago, and the details line up well. Normally the mass would be around 1.6 g., but you should expect a bit lower for obvious reasons

Real ones often show up holed, and unholed specimens get a considerable premium. Fakes are often off on some major details.

im 80% sure that cedid mahmudiye is real now, but can that ducat weight 0.06g less than other ones? I'm pretty lost here now.

Yes. Not unreasonable weight loss for the hole and wear (less than 2%).

The main design details (portrait, fonts, etc) on the AUstrian coin look OK to me. But not an area I know much about.
Also, I think I can see the base of an E at the bottom of the hole obv, which makes it Karlsburg mint: https://www.coinarchives.com/w/lotv...2a1155061dd8

Maybe you can find a jeweler who would test it for gold content. And the other forum where you posted these has a lot of knowledge on central Europe, so you may get more confirmation over there.

Edit: I know a lot of collectors wouldn't go near a coin with a hole, but if you got these for close to melt, you've got a couple of interesting gold type coins there . The ottoman type with a hole like that just went for 80 euro in a recent auction (before fees).
