I made PsychoticBoy an offer to buy one of his Casascius coins. I got this PM from PsyckoticBoy (so not the real one):
I offer you 1.5BTC for one 1BTC 2012 brass Casascius coin.
https://bitcointalk.org/index.php?topic=825604.40Ok, you have a deal
Payment address : 16Thq7oUYzHU2MhutbsKqzc2TdhvJRW5xu
After the funds have been sent drop me a pm with the transaction I.D and your shipping info.
Can get it off to you first thing Monday morning and will pm the tracking info.
Thanks.
He obviousely wanted to scam me, so please leave him negative trust.
