There are
fakes but genuine Alexander Tets in this condition are not hard to find and not expensive. There are some high-quality
fakes of all
types of coins that are hard to spot unless you find an identical twin but it's hardly worth it for a coin like this.
That does not mean that it is not a nice coin. Depending on where you buy it, you might spend $120-$250, of course it's always possible to get it for much less from someone who doesn't know
ancient coins or spend much more. That range is what I would consider reasonable. If you're
selling you should expect less, again depending on where and how you sell.
