Never mind all, I figured out where the coins came from. Bungie is just trying to bribe people into subscribing at Bungie.net.

From Bungie.net Penny for your Thoughts… We want your email address. “Why?” Don’t worry about it. We like you. Isn’t that enough? We promise we won’t give it to anyone else. If you give it to us, we’ll give you nine Strange Coins. If you already gave it to us, you’ll also get nine Strange Coins. Think about that before you take our Coins, only to opt out of letting us send you fanmail. We read yours. Ours contain presents, as well as challenges and some other fun stuff. Here’s how this works: Coins will be granted on Fridays – batched and rewarded. You have until August 30th to benefit from our seedy little bribe. We just want to keep in touch. And make sure you never leave us. Ever.
