Pic of the whole plant?
(I don't see the penny...am I missing it?). If the leaves are small, it's most likely 'Crosby's Compact,' but I suppose there are other compacts by now.

I couldn't find the penny at first, either. It's near the top of the plant, in the leaves. Funny, on my phone, the pic is upright, but on my laptop -it is turned sideways.

I believe this is regular Crassula ovata. If it were 'Crosby's Compact', the leaves would be about the size of the penny (or a bit larger).

Good eye, Rosemarie! ;-)
It certainly could be straight C. ovata. I was thinking the low light might have contributed to the larger, greener leaves.
