<p>[QUOTE="desertgem, post: 4888433, member: 15199"]Kentucky has the scientific answer, although a Platinum needle is better if you have one. From the appearance , as the photo tends to appear that some of the sides have stuck together a little is an indication of the pasticizers leeching our of the PVC ( which by itself doesn't cause problems, it is the plasticizers). Some that use such as SAFguard or SAF-something with flips means that there is still non-active PVC, but the very small amount plasticizers stay in and they are stiffer, but not inflexible like white pvc plastic pipes, connector, etc. that has no plasticizers. Make sure any acetone on a coin has completely evaporated or they may stick together as acetone reacts.</p><p><br /></p><p>And as long as your electrons are running sir, the SAF type of flips are excellent for long term storage, but if loosely shipping coins, it has been seen that any edge or surface can scratch or rub-line the coin, so pack properly, such as putting the coin in a polypropylene baggy about 2x2 from Walmart or 99store ( we call them drug bags locally) and put that in a stiff flip.
