I dont know about the two coins. Here is the 3 coin method in case you're interested.
Tthis is the method represented in Thomas Cleary's translation of 1796 Liu I-ming. In this book he does reference the Wilhelm/Baynes version for the yarrow sticks or Chinese (perhaps the 2 coin method, could be your source?) coins methods. I am a big fan of Thomas Cleary's work, always thorough and well put together.
3 U.S. Penny method:
1. formulate question.
2. toss coins.
tails has a value of 2
heads has a value of 3
3 tails = yin moving line = 6
3 heads = yang moving line = 9
2 tails, 1 head = yang solid line = 7
2 heads, 1 tails = yin broken line = 8
3. cast the coins six times total. the first toss represents the first line of the hexagram, starting at the bottom working your way up.
4. cunsult I Ching for translation.

For whoso comes amongst many shall one day find that no one man is by so far the mightiest of all.
