The last resort is make a mold, melt the gold in a crucible, ( it melts very easy), when in molten state,if there is anything floating on top of molten gold, slew it off, put it in mold and let it set. Take to a jewler, and have him certify it to 99.9995% as gold. Now have jewler stamp it as to purity. If asked where you got it, you melted down all the gold rings,watches etc. you collected over the years. they can't prove different,or you can just keep it, make a necklace out of it.You can always sell your gold to a jewler, a dentist.....got the picture? Now isn't that a bunch of s--- to go through, because you found some gold artifacts? the "Big Brother" society that is slowly taking hold in this country, has actually made you a criminal.Find out who your state and Federal reps are,find out where they stand on the issues of treasure, artifacts ect. If they are against your rights to keep what you find and, then tell them you will no longer support them, and you will advise all who you know, to following your lead!....Capt. Tom
