Cleaning out my mother’s house and found this in my step father’s coin collection.

5 state quarters: Oklahoma, New Mexico, Arizona, Alaska, and Hawaii incased in acrylic, in original box.

The set is in perfect condition.  No cracks , scratches, or chips in the acrylic.

Hard to photo these and capture the true cleanliness and shininess of the coins.  They are bright and shiny.

AI says:

This is a 50 State Quarters Silver Proof Set produced by the United States Mint.

The set features five proof-quality quarters, typically minted in San Francisco as indicated by the "S" mint mark.

These coins are composed of 90% silver.

 Sets like this were released annually between 1999 and 2008 as part of the 50 State Quarters Program.

The 2008 set carries a slightly higher value premium compared to other years in the 2000–2007 range due to two major factors:

1. The Finale Factor: 2008 was the final official year of the core 50 State Quarters Program, featuring the last five states: Oklahoma, New Mexico, Arizona, Alaska, and Hawaii. [1]
2. Lower Mintage: The US Mint produced fewer proof sets toward the end of the run compared to the peak years of the early 2000s, decreasing the total supply.
