You may know that I have been improving sets and working backwards from 2015.  I have found and documented 21 Case XX sets in 2008.  Collectors want to know value. of course.  On KnifeDB.com each of these sets has a price paid for the whole set as well as several actual prices for each knife.  The red stag set has the top value with over $200 per knife paid for the set or about  $1,600 total.  The NRA set has a per knife average price of about $105, with the other two sets shown having a slightly smaller value.  You can see all 21 sets with many actual prices on KnifeDB.com.  Become a member for less than a hot cup of coffee a month.
