1955 US Mint Proof Set
The 1955 Proof Set continued to experience a rapid increase in the number of sets produced and sold by the United States Mint. This year included an important packaging change for the set that would make it much easier for the Mint to ship sets and also easier for collectors to store their sets.
Each 1955 Proof Set contained five coins. These were proof versions of each of the coins issued for circulation during the year. This included the Franklin Half, Washington Quarter, Roosevelt Dime, Jefferson Nickel, and Lincoln Cent. The proof coins are typically found with brilliant proof finishes. The more desirable cameo and deep cameo finish coins were becoming more frequently encountered compared to the earlier years, however choice examples can still be elusive and drive high premiums.
The number of sets sold during the year was 378,200, an increase of nearly 150,000 units from the prior year. The US Mint issue price remained the same at $2.10 per set.
For the first part of the year, the 1955 Proof Set was packaged in the same small square box that had been used since the resumption of proof offerings in 1950. Later in the year, the US Mint introduced the flat pack style of packaging. The coins were all sealed within individual compartments of a single plastic pack, along with a foil Philadelphia Mint seal. The plastic pack was placed between two cardboard inserts within an envelope. This new style of packaging would be used for proof sets through 1964.
