Random #AliExpress finding...

So today I discovered why I was getting weird results in a circuit I was testing the other day. It turns out that some of the 1N60P germanium diodes I have are fakes. They appear to be just a plain silicon diode with a forward voltage of ~0.6V, rather than the actual article's ~0.25V.

They're in the right DO-35 glass package and they've been marked as 1N60P, so someone's gone to the trouble of faking it well - but I can't see why. It can't possibly be that profitable to buy genuine silicon diodes, remark them, and then sell them for just a few pennies extra, can it?

It's not like the sellers that remark a ten-cent opamp as a $10 part - I can see how that's profitable.

Weird.
