Chuck Connors appeared as the rancher Lucas McCain and Johnny Crawford as his son Mark McCain. This episode is titled "Tinhorn" and was first broadcast on March 12, 1962. Lucas takes up gambling to the surprise of his son Mark and his girlfriend Milly. At one point Lucas and a visiting gambler named Keeler play for a large amount of money. The coins on the table are prop or imitation coins resembling Spanish bust silver dollars which were minted from the late 1700's to the early 1800's.

A boy tells Mark that his father is playing poker at a saloon.

Mark sees Lucas seated at a table.

Keeler is a visiting professional gambler and he is accompanied by his girlfriend Rose, who works as a saloon girl. The previous night a farmer named Jesse Phillips lost a lot of money to Keeler. Lucas is attempting to prove that Keeler cheats at cards to get Jesse's money back.

Lucas visits his girlfriend Milly but she tells him that she will not date a gambler. Back at the saloon Lucas continues to play cards. The other players drop out leaving Lucas and Keeler.

Lucas offers to play a hand with Keeler and shows his cash.

The coins on the table appear to be imitations of Spanish "Bust" 8 reales or peso coins. These coins were minted in Spain's American colonies from approximately 1772 to 1821, and circulated in Britain's American colonies and the United States until the 1860's;
