Assuming you meant the 2.50 1849 liberty head gold piece. It can be worth as low as 200 bucks or as high as 30000. We would need good detailed pictures to give you an accurate value.
you will have to upload them using a computer. dont know why but i couldnt get pics to upload from the tablet either
