There are loads of these in the "number 1" category. They are all unissued and were released onto the market by French philatelists in 1923 after they were requisitioned in lieu of payment for the stamp order. The Soviets invaded Armenia and the stamps weren't needed in such quantities. They have also been forged and reprinted several times, and were genuinely issued in 1923 with numeral overprints.
Here are a few. Sorry but image optimiser doesn't do them justice. As you can see, there are quite a few shade vareties.
