I need to send some coins to PCGS and they require that the coins be sent in 2 1/2 by 2 1/2 inch mylar flips but the price they're asking for on the site seems a little pricey. Please recommend some places I can buy these at (other than a local dealer, of which I don't know any in my area). PS If this has been asked before, my apologies but I could not find any threads.
Most coin shops carry the mylar flips, along with a lot of other storage supplies, cardboard, 2x2s, mylar pages for binders, certified coin boxes, 2x2 boxes, etc.
