About this item
- Proof blanks are specially treated, polished and cleaned to ensure high-quality strikes. The blanks are then fed into presses fitted with specially polished dies and struck at least twice to ensure sharp relief, delivering coins with mirror-like finishes and exquisite details. Proof coins are struck for collectors and never released into circulation.
- Numismatists refer to a coin that has been evaluated and certified by a professional grading service as a "slab" or "graded coin." A grading service acts as an impartial entity, offering an objective assessment of the coin's condition along with official certification. The term "slab" specifically denotes the encapsulation of the coin in a secure, tamper-evident holder provided by the grading service.
- We are proud to offer a selection of Graded Slab Coins authenticated and certified by the highly respected American Alliance Coin Grading Service (AACGS).
