Coretek Museum Grade Currency Holders - Small, Medium and Large

Coretek flips and currency holders meet the highest standard in archival quality material available on the market today. To meet this standard, Coretek uses a polyester film that is 100% uncoated, colorless, biaxially-oriented PET. That means no plastic, no additives or UV inhibitors, no surface coatings, no absorbents or other contaminants. Coretek is a truly archival product line and represents the best practices in archival materials for coin and currency holders. All three sizes -- Small, Medium and Large come in packages of 50. Small holders are 5 1/4 x 3 1/8 Medium holders are 6 1/2 x 3 Large holders are 8 x 3 1/2 PLEASE NOTE: For Canadian currency, we recommend using the Large holders for Modern Canadian notes as the medium holders may be a little too tight for some collectors' comfort. If on backorder, please allow up to 4 weeks for delivery as product is shipped from the U.S.
