1959 US Mint Proof Set – Original Treasury Mailing Envelope | Sealed & Unsearched | Philadelphia Mint

An Unopened Time Capsule from the Philadelphia Mint — Still Addressed to Carol Sue

Somewhere in 1959, the U.S. Treasury mailed this Proof Set to a collector named Carol Sue Vondrasek. She wrote her name on the envelope in elegant vintage cursive — and then, for reasons lost to history, never opened it. Over 65 years later, it's still sealed. That's your opportunity.

This is a genuine, untouched 1959 United States Mint Proof Set in its original kraft paper Treasury Department mailing envelope, postmarked Philadelphia 30, PA. The envelope is fully intact. The coins inside have never been touched by human hands since leaving the Mint.

What's Inside (Still Sealed):

• 1959 Lincoln Memorial Cent — the very first year of the Memorial reverse design | PR69 examples start around $150+
• 1959 Jefferson Nickel | PR69 examples start around $100+
• 1959 Roosevelt Dime — 90% Silver | PR69 examples start around $150+
• 1959 Washington Quarter — 90% Silver | PR69 examples start around $200+
• 1959 Franklin Half Dollar — 90% Silver | PR69 examples start around $400+

All five coins are mirror-struck Proof gems, protected in their original cellophane flat-pack with the classic U.S. Mint data card. If any one coin inside grades at PR69 — entirely possible given 65+ years of undisturbed storage — the individual coin value alone could far exceed the price of this sealed set.

Specifications:

• Year: 1959 | Mint: Philadelphia

• Silver Content: 0.6148 troy oz (Dime, Quarter, Half Dollar — 90% silver)

A must-have for type collectors, silver stackers, and anyone who loves the thrill of discovering what 65 years of untouched Mint storage has preserved.
