Thanks for checking into it so thoroughly. That's what I live about this site. It's populated with great people. I wish I hadn't misplaced the COA, assuming it came with one. At first, I thought it did but now I'm doubting myself. I didn't know it was something the Mexican government distributed periodically. I believe I paid about $28 for it so I can't complain about getting a bad deal, I suppose. I just was curious re: its rarity.
If you haven't noticed by now, I don't proofread veery well and I apollogize profusely. (;>D
