The gold bar is an item featured in putt-putt travels through time.
Silverado Sam may be panning for gold in the river using Putt Putt's lunchbox. To retrieve it Putt Putt must find some gold. He can visit Merlin, supplying him with the required stones for his alchemy machine, where a bar of gold can be produced. Putt Putt can then place this in the river for Sam to find.
