Denis don't beat yourself up, it's a pretty rare part. I was VERY lucky he took my offer, things usually don't work out like that!
Yeah, I know you are right and I don't regret forking out the cash for it. It's just odd that I pitched him three offers and he declined each one. I did not know this until going for the pg but eBay only allows an offer, a counter offer from the seller and a followup counter offer from the buyer. I think after that you've reached the max.
Oh well, we both have Bicentennial pgs now, back where they belong!
I can't imagine how rare the '76 Bicentennial pg is.
