In actual fact, the term "penny turtle" is just the name of baby turtles. So depending on the type of turtle you have, it can grow to different sizes. If you're looking for a small turtle/terrapin, I highly recommend the musk turtle, as it grows to :
Females - 6-10"
Males - 3-5"
I have had a musk turtle for seven years now and at four years old he stopped growing at 3". He's very friendly and likes to be picked up, although when put with another turtle, they do get aggressive.
In conclusion, penny turtle's are quite rare to buy, I'm from Essex and I assure you they aren't for sale in the U.K! I got my ex-girlfriend a penny turtle but I ordered it from the states and it cost me $130!! so they aren't the cheapest pets either.
Hope this helps!
