The hourglass was used on Wu Zhu coins from 118BC to the 400s (and some later). But the character to the left I can't place on any coins.
On the other side the left character looks roughly standard, but the right character is unusual, and those don't connect to the hourglass.
Seems like a mishmash and not trying to copy something specific.
