SAFLIP archival-quality coin flips

SAFLIP coin flips are made from archival-quality, inert polyester plastic designed for long-term coin storage. Introduced by E&T Kointainer Co. in 1980, SAFLIPs were the first double-pocket MYLAR coin flips and remain a popular choice among collectors, dealers, grading services and museums.

Sizes and specifications

• Available in 2 × 2-inch and 2½ × 2½-inch sizes

• Made from durable, 5-mil-thick polyester plastic

• Double-pocket design for coin storage and identification

• Can be heat-sealed using a standard impulse-type heat sealer

• Acid-free identification inserts available separately

Why choose SAFLIP coin flips?

Archival-quality material

SAFLIPs are manufactured from polyethylene terephthalate (PET), commonly known as polyester or MYLAR. This stable, chemically inert plastic is widely used for archival storage because it does not readily react with stored materials.

Protection against tarnishing

PET allows very little gas to pass through the plastic, helping reduce exposure to the surrounding air. When properly heat-sealed, SAFLIPs provide an additional barrier against environmental contaminants that can contribute to tarnishing.

Durable construction

Unlike thin, flexible storage bags, SAFLIPs are made from thicker, more rigid plastic that provides added physical protection. PET also has high tensile strength, making it difficult to stretch or tear.

Designed for safe coin handling

SAFLIPs are designed to minimize the risk of scratching, including on proof coins. However, coins should always be inserted and removed carefully to avoid contact with the edges of the holder.

Clean manufacturing process

SAFLIPs are manufactured under strict cleanliness standards to minimize dust, oils and other contaminants that could cause spotting or tarnishing over time.

Heat-sealable pockets

SAFLIPs can be sealed across the top of the pocket using a common impulse-type heat sealer, providing additional protection against air exchange and contamination.

Used by professionals and institutions

SAFLIPs have been used by leading grading services, coin dealers, auction houses and museums, including:

• Professional Coin Grading Service (PCGS)

• International Coin Certification Service (ICCS)

• Canadian Coin Certification Service (CCCS)

• American Numismatic Association

• Heritage Auctions

• Littleton Coin Company

• Royal Ontario Museum

• Glenbow Museum

• Harvard University

• Smithsonian Institution

Their widespread use reflects the importance of choosing stable, archival-quality materials for long-term storage.

Additional information

Rainbow or oily appearance: SAFLIP pockets may occasionally display a rainbow-like sheen. This is an optical effect, not an indication of oil or contamination. Independent laboratory testing has confirmed the absence of these contaminants.

Identification inserts: Acid-free identification cards are available separately. These are designed to resist yellowing and avoid releasing sulphur compounds that could damage coins.

A reliable choice for long-term storage

Whether you're organizing an everyday collection or protecting valuable numismatic material, SAFLIP coin flips offer durable, archival-quality storage with the convenience of a traditional double-pocket holder.
