Hey Kickstart, sorry I have no info on where to get the best price for your halves (I have never sold a coin since I was a kid). However, I did get a half last Friday that had one of those aunt chiladas stickers on it, and it looked like it had your autograph on it! I went ahead and signed it as well. I have initialed maybe ten of these coins over the past year. Aunt chilada must be fairly new to crh, as I used to never see those stickers... Gpurs
