The #1 coin envelope in white is the smallest format for single-item storage and cataloging where presentation matters. At 2 1/4 x 3 1/2 inches, it holds exactly what you need it to hold: one coin, one stamp, one small gemstone, one watch component, one seed sample, one fastener. The white surface is cleaner than brown kraft for printed labels, photographs in documentation workflows, and any professional or retail context where brown kraft looks out of place. This version is 28 lb white wove (110 gsm), short-side gum flap, no window, blank. Available with custom printing from Business Envelopes. Free shipping on every order with no minimums.

White Coin Envelopes: Why White Over Brown Kraft at This Size
Brown kraft is the traditional coin envelope material and it works well for most storage applications. White coin envelopes are the right call when the environment or the workflow calls for it.
Jewelry counters and gemologists use white for single-stone storage because the white background shows the item clearly when the envelope is opened and held up for inspection or photography. A diamond or colored stone against a white background is visible. Against brown kraft it can get lost in the color contrast. Medical and pharmaceutical environments standardize on white because everything else in the workflow is white and the color consistency matters for organized, inspectable workspaces. Archivists and philatelists who photograph individual stamps or small specimens for cataloging get cleaner images on white stock than on the textured brown surface of kraft. Retail operations that hand a sealed envelope to a customer as part of a transaction look more professional doing it in white.
The 28 lb stock on this white version is the same weight as the brown kraft version of the #1. It's not a lightweight envelope. It holds its shape through handling, keeps small items secure, and gives the short-side flap enough body to open cleanly and close firmly after moistening.
No 1 Coin Envelopes: What That Search Means
"No 1 coin envelopes" uses the same "no" prefix as "no 10 envelope" or "no 9 envelope," where "no" is shorthand for "number." It refers to the #1 coin envelope, 2 1/4 x 3 1/2 inches, the smallest size in the standard coin envelope lineup. Buyers searching this phrase are typically confirming the size designation before placing a bulk order or looking for a supplier that stocks the #1 specifically, since most local retailers carry the #7 more reliably than the smaller #1.
We stock the #1 in both white and brown kraft with same or next day shipping on blank stock, no minimums, and bulk pricing that drops per-unit cost as quantities increase. No need to special-order from a local supplier or wait on a stocked quantity to come in.
