Counterfeit Or Real?

It's hard to assess coins from photographs with 100% guarantee, but I see nothing about Elizabeth I sixpence that would raise a red flag. Those are fairly common, everything seems to be in place, the crescent MM is correct for the year.
I can't quite make out the legend on the halfpenny to say much about it or to attribute it (looking at Britannia and the king's effigy I'd venture a guess of George II but I don't see any confirmation of that in the legend), but that wouldn't be worth the trouble of counterfeiting either. Unless it's a contemporary counterfeit in which case it wouldn't be any less valuable to collectors than a real one.

Cud Wild Both coins look real to me - at least no big red flags.

Better (larger scans) might show something BUT they look good. The English coin of Elizabeth I uses designs that are consistant with the real types from this era. There are hammered and milled coins issued for her reign and this one looks typical of the more commonhammered types. The way the coin refects light, the color and the dark patina all look as they should.

The half Penny is definitely a Connecticut variety. It is not clear enough to type but would be worth in the $100 range minimum. There are many very rare varieties of this coin that can be identified by die type. Maris did a great job developing the die sequence for these coins and the more recent book by David Bowers on US colonial issues adds a few more dies. It should be relatively easy to determine the die marriage and relative rarity.

Thanks for the replys. I was figuring if the sixpence was real its worth about $20. Is that about right? The colonial coin is also rainbow toned does that increase the value at all? My wife is a professional photographer so shes going to take a better pic of the coin for me and Ill post it on the US coin section.

It probably was cleaned at one point in time. I didnt pay much for these coins so I'm happy either way.
