I bought this two months ago.

Unfortunately it seems that about a quarter of the flan was broken off in antiquity, so the last part of the obverse legend is missing and part of the year date (LK) on the reverse is missing, as well as a chunk out of Cerberus.

Giving it some attention, I noticed how the style of Commodus' beard resembles more the style seen in the later busts of his father, Marcus Aurelius, and imitated by Septimius Severus, like "icicles" as Furious Rufus would say.
Most of the Billon Tetradrachms of Commodus that I have so far aquired have his beard quite short.

Here is the info on it:

Obverse: MA KOM ANTω - CEB EVCEB, laureate bust facing to the right.
Reverse: Serapis, seated to the left, holding a sceptre with his left hand and his right hand over Cerberus, seated to the left. LKΘ in the upper left field.

Weight: 9.90 g, Diameter: 22 x 25 x 3.2 mm, Die axis: 0°
Mint: Alexandria, year 29 (LKΘ),
struck between 188 -189 A.D.
Reference: Milne 2680

Even with the damage this is still an excellent coins. The details of the emperors face and beard are nice and sharp.

It seems to me that this coin was struck just below it's paste range.

A good looking coin depite the missing elements.

Finding nice examples of Commodus Tets isn't easy.

I have bought a couple of my own recently. A year 24 with the shorter beard and and Year 29 where you can certainly see the longer beard.

Surely "sel_69I" not all your posts are of such vacuousness?

The 'paste range' of an alloy is the temperature range where the metal with the highest melting point has solidified, but
the metal with the lowest melting point is still fluid.

The alloy is said to be in it's temperature 'paste range' if the temperature is between the lowest and highest melting points of the metals which make up the alloy.

An alloy that is in it's paste range is very soft, and is easier to stamp an image on it. Less die pressure is required, and die life is extended.
Considering the fact that ancient coin dies took a lot of effort to fabricate by hand, die life is critical. Therefore heated blanks were often used.

In the case of the coin pictured, I think that is was struck when BOTH metals which made up the alloy had already soildified.
The blanks, if relatively thick, can become stressed under the extra striking force required to impress the images on them.
It seems that some of the blank has spalled off, perhaps not long after striking.

'Paste range' is a term most often encountered with the use of soldering.
