A Penny For Your Thoughts
Fish up the copper coins listed below from the Dalaran fountain.
A Penny For Your Thoughts is a 10-point achievement earned by fishing up a collection of copper coins from the Dalaran fountain, located at 52, 65 in Dalaran.
Reach Required Fishing Skill
You need a fishing skill of 430 to fish at the Dalaran fountain at 52, 65.
Use Gold Coins for Efficiency
When you fish up a gold coin, use it by throwing it back into the fountain — this temporarily increases your chances of fishing up more coins and can save you several hours of fishing time compared to never using them.
Fish Up Copper Coins
Cast your line repeatedly into the Dalaran fountain at 52, 65 to fish up the required copper coins, which include 
A Footman's Copper Coin, Ansirem's Copper Coin, Danath's Copper Coin, Eitrigg's Copper Coin, Alonsus Faol's Copper Coin, Attumen's Copper Coin, and Dornaa's Shiny Copper Coin, among others.
Tips
Not throwing gold coins back into the fountain can result in upwards of 5 hours of fishing time to complete the achievement — always use gold coins when you fish them up.
