For sale is a 1978-D (Denver Mint) Clad Washington Quarter in Original Mint Cello and Uncirculated. The protective plastic flip is for SHIPPING PURPOSES ONLY! I attach the plastic flip to the inside of the letter with adhesive, if shipping individually, to prevent the USPS sorters from jamming in the machine and delaying, damaging or even ending the order. If the coin is undamaged and it arrives to you but the flip is scuffed or has adhesive stuck to it - IT HAS SERVED ITS PURPOSE. I have to stress this as it became an actual issue, I will not send a replacement flip for the coin as it would defeat the purpose of selling these a lower cost. I ship eBay Standard envelope with tracking. Thanks for looking and have a great day.
