Coins are struck, not etched which involves removing metal by use of acid, so it's not clear what the question is asking. Some possibilities:
If your coin has a small picture of JFK or someone else facing Lincoln, it's a novelty piece made outside of the mint and has no value to a collector. If it has the same design but struck twice on the same side, it could be a somewhat rare double strike but it would have to be examined in person by an expert to say for sure. And if it has Lincoln's image clearly shown on both sides it's a fake called a magician's coin.

All 1968 cents were struck in bronze. If your coin is silvery in color it's almost certainly plated. In addition if it were made of aluminum it would weigh only about a gram, 1/3 the weight of a cent from that year. The only aluminum US cents ever made were experimental pieces in 1974 and none were ever put into circulation.

The state was stamped on it after it left the mint. It has no collector value -- novelty value is perhaps 25 cents.
It's almost certainly either a privately-issued piece or a genuine penny that was altered. Either way it has no collector value.
It's a novelty coin made by a private company that has no collectible value, but it's still one cent.
Because the legality of the coins is in doubt and currently are illegal to have, a value can't be given.
