you could put it in water and see if it tarnishes quickly?\n\ngold is relatively stable, and doesn't tarnish. you could also try to test it's electrical conductivity if you have an ohm-meter. gold conducts electricity very well. you may need more info to do this though.\n\ngood luck

I would take it to a jeweler, there is no way to be able to tell if a diamond is real just by looking at it. They will be able to test it for you. It might also cost some money, just depends on the jeweler.

Something that is gold should have a stamp mark somewhere on the bottom.  As far as solid, there should be another stamp mark saying what the purity is.

Art dealers should be familiar with specialists in this area.\n\nOne quick test you could do for yourself:  Does it appear to have been written with a ball-point pen?  If so, it is most likely a fake.

If it is genuine, I think it will be impossible to demonstrate it.  \nIf it is not genuine it will possible to demonstrate it.\n\nSo we will only be sure after they say that is not genuine.

The real value of any currency is measured by checking it against the price of gold in that currency.  This is the only litmus test of real wealth that can be easily measured.  As of right now $1.00 is worth 1/545 of an ounce of gold.  \n\nAnother way to check was with something called the M3 index, which is just a count of all the US currency in circulation and in reserve in the world, but the Treasury Department just recently stopped reporting that number presumably so nobody would panic when the dollar gets wasted in the world economy soon.

One easy quick & easy way to find out is the streak test. Rub the mineral in question across an unglazed porcelain tile. If the streak it makes is black then it is pyrite (fool's gold). If it is golden yellow then you have gold. You can find these tiles in your local home & garden shop or hardware store.\n\nAnother simple one is the hardness test. Gold has a hardness of 2.5 to 3 on Moh's Scale. Pyrite is 6 to 6.5. Glass has a hardness of about 5.5. According to Moh's scale you should be able to scratch glass w/ pyrite but not w/ gold. Pennies can also be used as their hardness is about 3.5.\n\nGold is found in several different forms or habits. It can be dendritic (vein-like) or massive as in nuggets. Upon examining pyrite more closely (perhaps w/ a 10x magnifier) you will see that while it resembles a gold nugget it is actually made up of many tiny little cubes.\n\nGold will not cleave whereas pyrite will. Cleavage is simply how a mineral breaks evenly due to weaknesses in its crystal structure. Pyrite has cubic cleavage so that when it is hammered it will come apart in perfect little cubes.

They do have the ability, but they will probably confiscate the money if it is found to be fake.  There are cheap devices you can get to check money yourself.  They are called Counterfeit Money Detection Systems and the lower end ones sell for under $20.00.
