....this will help you get a ball park clue on the grade. http://www.pcgs.com/Photograde/#/Buffalo/Grades
Anywhere from about $10 to about $4,000 or more or less pending the condition, grade, weather, availability of purchaser, time of day. If you don't have a camera and/or just don't know how to post a photo, try describing your coins as best as you can. For example with that nickel, is the date clear? Is the Buffalo's horn full? How much clarity is there in the Indian's feathers? Is the to of the Buffalo's shoulder clear? What about the writing on the edges? These are only examples of what you could say if no photo is given.
