http://www.goldcoinbalance.com/blog NEWS FLASH!!! Goldcoinbalance.com has discovered a fake Gold Eagle one ounce that passes the tests for weight, size and thickness. Our GoldCoinBalance Guarantee has always stated that we would pay the spot gold price for any gold coin that passes all three tests of the GoldCoinBalance. We were so confident in our product's ability to spot the fakes we offered this guarantee. However, we recently received a coin and letter from a customer who had purchased a Gold Coin that passed the tests, but was a FAKE Tungsten Coin. So unfortunately, we can no longer buy Kugerrands or American Eagle Gold Coins that pass the Goldcoinbalance tests. Someone is making Tungsten core fake coins that do pass the test!!! Buyer Beware!!
It was only a matter of time :/ They might want to remove the following from their homepage now- "No other metal can look like a gold coin and pass the 3 tests in the Gold Coin Balance. We guarantee it!"
