yes intellectual copyright applies to images taken by the author of material in his possesion.....however as much as intellectual copyright exists it can be controlled by corporate copyright. an example of this is when i photograph at premier league football matches, i own the intellectual copyright of the images i capture but am governed by the rules of the premier league, an example being the number of images i can post on my personal website without having to pay for a licence. the same applies to buildings, whilst i can capture images for example on national trust land and own the intellectual copyright of those images, what i can do with those images is controlled by the national trust and what licence i may have to pay them,  for earning monies from their property. it is also possible to have your intellectual copyright removed in certain circumstances, such as under the terrorism laws if you were photographing a sensative subject such as a military installation, a government office block on the north bank of the thames!!!...... youre question though is clear cut......you owned the coin, you own the intellectual copyright to the image you captured.  you can publish.
