10 quarters to look for in pocket change

Can you help me out with this please? Collectors might assume this is referring to the US Mint facilities at Philadelphia-Denver-San Francisco, but this is not the case. If so, its worth face value. There are subtle variationseven among coins with the same year and mintmarkand recognizing these distinctions can pay off handsomely. Almost everyone has a box, can, jar or piggy bank full of spare change. There aremore than 60 different reverse varieties concerning the 2005 Minnesota quarter extra tree error, and they come from the Philadelphia, Denver, and San Francisco Mints. Many coins become damaged while in circulation. https://uploads.disquscdn.com/images/0b432fe938c689db1b1bb2725aa9286633e29412ea08468505c47059b6eaf58a.jpg https://uploads.disquscdn.com/images/0930879a4f1750ba45a3286f3bcb020c412cb041039f8f8be03c68f43d9d1f2e.jpg, Any value to the two pictures below, the 1982 has D, but is very worn, Im afraid both of these quarters are worth face value in this condition level, I came across a few old coins not sure if they are worth anything maybe you could help me out, it wont let me upload my pics do you have an email I could reach out to please.
