2. Scoop up some Tarn X; which makes those pennies nice and shiny. I split the pennies 50/50, so some were tarnished, others squeaky clean.
3. Spend the next few weeks after work gluing pennies to the table. I made a seam to bend the pennies with a bolt cutter to put them on the edges.
4. I recommend finishing with an acrylic coating, otherwise those pennies get gross fast with the daily wear + tear of a coffee table.
Take that to the bank.
