I didn't bother to read the whole thread, but if I had a card #'d to 5, I would not take $20 for it unless it was a dead, dead common. $200 is a joke.
If that was my card, I would have $50 or BO and probably accept $35, maybe a smidge below.
My philosophy on low numbers like that are, if you don't want to pay my price, find it elsewhere. Seriously, it's #d to 5. There are only 5 of them and it's a jersey card. If you don't buy from him, what are the odds you will see another one?
I see he sold it for $20 which I think is way too cheap. Just my opinion, take it for what it's worth.
