48 1955 Red MAntle Correct found by Armour Al

We can expect Armour coins of rare color to be scarce or missing from the known sets ...well ...because by definition they are scarce. This should be a random occurrence, i.e. different players missing in diff rare colors, and for the most part that is true.

But...why would a player be missing in a common color ? That is the case for the Mantle correct variations where existence appears to be in the trend :
Navy=Aqua>>pale green=black >>>yellow>>>> orange & red. In fact, up until a few weeks ago no  red correct L-R  was known to exist.

Then it popped up on EBay Armour Al grabbed it before any of the rest of us even knew it was up there. It certainly is not in NM, but it certainly is the only one known to exist.

Below you can see it sitting between Mantle incorrects in orange and dk red.
