What we have is more valuable than silver or gold
When Peter spoke to a lame beggar he made it clear that he did not have any silver or gold to give, but instead he had something much more valuable to him. He had healing in the Name of Jesus. He gave that to the beggar.
“Then Peter said, “Silver or gold I do not have, but what I do have I give you. In the name of Jesus Christ of Nazareth, walk.” Taking him by the right hand, he helped him up, and instantly the man’s feet and ankles became strong. He jumped to his feet and began to walk. Then he went with them into the temple courts, walking and jumping, and praising God. When all the people saw him walking and praising God, they recognized him as the same man who used to sit begging at the temple gate called Beautiful, and they were filled with wonder and amazement at what had happened to him.” (Acts 3:6-10 NIV)
