I dont really know too much about these stones so I am looking for as much information I can get from anyone that is knowledgeable. I am in arizona so I'm assuming they are from here but I dont know for sure if they are real or fake so any help is much appreciated thank you so much.

I have a silver horse statue I was given about 10 years ago and told at the time it had belonged to the person's grandfather. It is mounted on a wooden base. I am just curious if it is worth anything. It stands about 7.5" high and is about 8.5" long. The statue is bolted into the wooden block with two long screws that can be seen on the bottom of the block (see pics). The whole piece is rather heavy and very sturdily built/solid.

I received this plate from my mother. 

This was in the barn of the property we purchased.  Don't know if it works, but we know from town folks that the person who had this printed a town newspaper.

Hi i recieve this set from a friend im not sure if its a tea set or a coffee set. It comes with a hot water pot, a milk jug, a sugar bowl, 6 cups and 6 plates. There is a stamp on the bottom that reads "OLD WILLOW MADE IN ENGLAND ADDERLEY WARE". It is a Blue and White set. I would love to know the average price and a bit of history about it if possible.
