Also, looking at the picture of the coin shows where they may have landed. IMOO it looks like they landed in what is now labrador. Compare the coastline of north america and the coin.





Also, here is a chart of currents that I have drawn a scenario on.


TO
1. An flotilla of exploration vessels from Carthage sets sail for southern africa.
2. The cross through the straits of Gibraltar
3. A storm has begun to batter the Carthaginian flotilla.
4. The storm disables the carthaginian ships and they begin drift in the powerful current.
5A. They have been drifting for a week or two now.
5B. The current has slung shot them into a lateral drift parralel to the north american coast.
6. They are then oaring north against the current as land is in sight.
7. The land in canada!!!

From
1.The set sail from canada.
2. Light shear currents carry the ship south along the coast
3. Current turns and carries the ship back towards europe.
4. Currents carry ships back towards iberia
5. The straits of gibralter are within sight.
6. They return towards the mediterranean.
7. They reach carthage.
