Nice! Always fun to find weird things when hunting. It's worth more then the half they didn't put in there, too!
Wikipedia has the Kennedy half at 30.6 mm and the UK penny at 31mm (although 30.8 mm may be more accurate for the UK penny?) Cool find
It never ceases to amaze me at the lengths that some people will use to try to cheat their bank. Chris
Interesting coin, but worth far less than 50 cents, so you will have to decide if it was worth finding in a half dollar roll.
Many of those old English 1 penny coins are worth $1. In a little better condition. I think for 50 cents you broke even.
Maybe it is just the coin dealers I did business with. Some of those guys will not even buy coins like that, others will buy them for 5-10 cents then put them in a bucket of cheap foreign coins for 50 cents apiece.
Condition is VG at best and $1 is retail. That's why I said 50 cents. As an extra coin in the roll, it's a nice find. I have a couple of these (1917,1919) and they are nice coins.
