You are bidding on a scarce key‑date 1905‑S U.S.–Philippines One Peso, Allen‑16.06 Curved Serif, certified PCGS AU55 in the special VaultBox holder.

Struck at the San Francisco Mint under U.S. administration, this large silver peso (0.900 fine, 0.78 oz ASW) is one of the most sought‑after issues in the U.S.–Philippines series.

PCGS has assigned this coin a straight AU55 grade, placing it solidly in the “About Uncirculated” range with strong remaining detail and attractive, original circulated patina.

The Allen‑16.06 Curved Serif variety is the normal but still low‑population 1905‑S die style; Greysheet and specialty references note that all 1905‑S pesos are uncommon because rising silver prices led to heavy melting and limited survival.

Recent AU‑range 1905‑S peso auction prices, along with Greysheet AU/MS levels and PCGS population data, support a collector‑to‑collector value in the high‑$1,000s to mid‑$2,000s for straight‑grade PCGS AU pieces like this example.

For the advanced U.S.–Philippines or key‑date type collector, this coin offers an outstanding opportunity to acquire a certified AU55 1905‑S peso without stepping up to Mint State money.
