Despite the support of the director of the mint and the treasury secretary-appointed CCCAC, the Treasury Department opposed the 50 States Quarters Program, as commemorative coinage had come to be identified with abuses and excesses. The mint's economic models estimated the program would earn the government between $2.6 billion and $5.1 billion in additional seignorage and $110 million in additional numismatic profits. Diehl and Castle used these profit projections to urge the Treasury's support, but Treasury officials found the projections to lack credibility (at the program's conclusion, the Mint estimated the program had earned $3.0 billion in additional seigniorage and $136.2 million in additional numismatic profits).
