VAMWorld 2.0

I'm a bit confused by the individual pages. The pages suggest they are different - with the 18 being a Hot 50 but the 30 not - but the pictures and descriptions are confusing.

As I read them I see they share the same obverse (clearly stated on the 18 description), yet they also share a 2 olive reverse with strong doubling of the eagle's left wing and nostril. Presumably the latter being what makes the 18 a Hot 50, because if it was the obverse that made it worth of the list, the 30 would also be a Hot 50?

I have a coin that has clear VAM-18 markers (see below) but how do I rule out the potential that it is a VAM-30?

Thanks!

First, overse pictures:

Now the reverse pictures:

It a VAM 18. But you've come across one of the defining examples of an 'evil mimic'.

Thanks! I'll happily take the 18 - crikey the 30s are, indeed, evil mimetics because the reverses are almost spot on to one another.

Again, happy with an 18...
