Wallet
Actually part of the huge eCommerce icon pack from Rocket Theme, which is linked on the Download button below.
Wallet is a free Icon design resource made by Dribbble user Katya Prokofyeva. As far as I can tell, its license is Creative Commons Attribution-NoDerivs.
Helpful hint: Dribbble users are nice. If the license is unknown, it is usually because they forgot to mention it explicitly; not because they were being stingy. Ask nicely and they will probably allow you to use it.
