Fred: I have a couple hundred Harley-Davidson chips. The early ones with hot stamp silver and gold in the centers were sold by the dealers from $2 to $3 each. However, the chips evolved over time and the inserts were color illustrations and the price obviously jumped to $3.75 to $4.00. Several of our members have been collecting for years. My main collection focuses on Caribbean islands. Recently bought some from Cozumel and Roatan and paid $4 each for the Mexican chips and $5 for Honduras chips. Here's 3 generations of chips over seven years.
