Solution:

Coin $C$ is drawn as a complete, unbroken circle, so nothing covers it and it lies on top.

Reading the remaining overlaps, each coin's uncovered arc shows it sits above the next: $C$ covers $E,$ $E$ covers $D,$ $D$ covers $B,$ and $A$ covers $B$ while lying under the others. This gives the top-to-bottom order $(C, E, D, A, B).$

Thus, the correct answer is E.
