Here's a great pair of matching 7-0 repeaters. 

I purchased these two notes separately. When I saw they were both from Series 1988A, I figured they were initially released and purchased together. However, a check of Bureau of Engraving and Printing records indicates these blocks from neighboring Federal Reserve Districts were printed 16 months apart. The HC run from St. Louis was printed in February 1991 and the GK run from Chicago in June 1992.

So they were released separately, each saved in gem condition for 32-33 years, and recently united!

Note that the Chicago 77077707 repeater is on its matching 7th District!  

The notes will be well-packed and shipped by USPS Priority Mail with tracking. Bid with confidence; this is my 25th year buying and selling on eBay; I have maintained a perfect rating.
