I can't see why people should want to be on the banner ? You lose copyright on your picture (or have things changed). Copyright gives you the chance to make a little more off a find. I don't mind publishing pictures of my gold finds as I have so many that I still retain so can retake a picture at any time. Items that the state have decided they want to hold on to I only have a few pictures of.
Now I've found Roman statues, bronze and silver washed, celtic bronze statues etc but all would be banned, as I assume my Spanish treasure fleet coins from the Florida beaches would be, because they were found several years ago. I don't worry what goes on the banner and totally ignore it because "find of a lifetime" in the U.S. could mean the most common Roman coin we find everyday over here, while in the U.S. it could be the only Roman find ever made in that State so IS something to be proud of. Meanwhile most of the British finds are worth little however old, because they are picked almost off the surface of fields (so little skill needed to find them) that have been ploughed for hundreds of years and are worn out and damaged.
