Can anyone tell me how I would check the public address on my old Casascius Bitcoins? I have 3 total cons but I am unable to find where or how to check the public addresses on the coins for they only have 8 characters. I have listed all 3 of the pubic addresses below if anyone can help. Thank you in advance.
1) 134xRg9x 2) 1359wf1p 3) 1348FHtv
Thank YOU!
