About 6 years ago members of my local metal detecting club found a small hoard of predominantly Henry 8th coins here in Somerset. Following protracted delays in processing them through the Treasure process they will be valued shortly. The finders would like to know if the values might be a little higher if they are associated with being part of a hoard. There were 2 gold coins (half sovereign and crown of the double rose) and about 9-11 groats (one wasn't Henry 8th) and part of a silver bosun's whistle. Photo shows some of the coins found.
Are Hoard Coins worth more than others of the same type ? Only when the person buying one thinks it is. What you're talking about is provenance, and to some that means something while to others it means nothing. It's like asking is this coin worth more because so and so used to own it ? To some it is, to others it's not. To my way of thinking, it's what I call the "cool" factor. Some think being cool is worth something, others don't. But no matter what ya call it it's the same thing.
