You are getting a PCGS sample slab given at the set registry luncheon held at the January 2018 FUN show. Holds a 1918-S Wheat cent.
Most luncheon slabs of this type have 1918 Philadelphia cents. Only a few have 1918-S or 1918-D. I track eBay luncheon slab sales in a spreadsheet. Since the slab was issued, 15 have sold.

Could be quite a while before you see another of this type.
Luncheon slabs are avidly collected. Holder is in top condition.
I ship promptly and have a perfect feedback rating in 25 years on eBay, so buy with confidence.
