Slabbing chips or strikes is not an acceptable practice with most members. The only one doing this at this time is a person calling themselves "SGS" and is an absolute scam. The "slabs" are sealed with a sticker and he only has one grade "CS100". I would stay away from this persons eBay auctions. As far as not being a striker. We all started with one. You will meet a lot of great people in this hobby so jump in with both feet. You can go to www.silverstrikers.com for some great info and help.
