- The day after the 28th annual Gilroy Garlic Festival, online bidding started as low as .99 cents (plus $6.50 shipping) at eBay.com for a Herbie Bobblehead doll – the most popular festival souvenir for five years running. Each year, the bobbleheads appear on the site within days of the festival, and shoppers can still buy bobbleheads from the past several years. This year's bobbleheads may outpace others in long-term value, since it's the first year that festival organizers imprinted unique numbers on each of the dolls in the limited series.
