Executive Order 11110 was not fully implemented as instructed primarily due to subsequent actions taken by the Treasury Department and Congress. After President Kennedy signed the executive order on June 4, 1963, which delegated authority to the Secretary of the Treasury to issue silver certificates, there were changes in policy and legislation that affected the implementation of this order.

One key development was the halting of silver certificate redemptions for silver dollars by Secretary of the Treasury C. Douglas Dillon in March 1964. This action essentially limited the practical impact of Executive Order 11110. Subsequently, on June 24, 1968, all redemption in silver ceased, further diminishing the relevance of silver certificates in circulation. Additionally, in the 1970s, remaining silver dollars were sold to collectors for their numismatic value.

The final blow to Executive Order 11110 came with Congress repealing its legislative authority through Public Law 97–258 in 1982. This legislative action effectively nullified the provisions outlined in Executive Order 11110 by removing the legal basis for its implementation. Furthermore, President Ronald Reagan’s Executive Order 12608 issued on September 9, 1987, formally revoked the text added by Executive Order 11110 to Executive Order 10289. This revocation solidified the end of any remaining influence or relevance of Executive Order 11110 within U.S. monetary policy and operations.

A combination of actions taken by subsequent administrations, changes in legislation, and shifts in monetary policy rendered Executive Order 11110 obsolete and ultimately prevented its full implementation.
