When did soda bottle deposit change from 1 cent?

The soda bottle deposit in many U.S. states changed from 1 cent to higher amounts in the late 1970s and early 1980s. For example, in Michigan, the deposit increased from 10 cents to 20 cents in 1986 for bottles and cans. Other states have varying deposit amounts, but many began to adopt higher deposits during this period to encourage recycling.
