Silverback Cipher
 
 
 
Silverback hunters should be familiar with the “pigpen” or masonic cipher, which is a simple substitution cipher exchanging letters for symbols based on a grid.

This cipher can be used to decrypt directions and secret codewords at FBZ geocaches!

Project A.P.E. Gold Geocoin Tracking Bug ImageCurrent GOAL:
Operatives can discover this intelligence (codename GOLD) as part of the A.P.E. 56 classified Operation Silverback mission.

Its discovery is worth 30 points towards an operative's rank here on this Web site!

About this item:
This Project A.P.E. coin does not physically circulate but photographic proof of its existence can be discovered at the Simian Guerrilla Task Force's Forbidden Zone (FBZ) A.P.E. 56 "Little Green Men" Top Secret Geocache (TSG).

Its true whereabouts are unknown, but most believe this highly coveted Gold Project A.P.E. geocoin is stored under maximum security in an underground, fortified bullion depository east of SGTF headquarters. The tracking code can be found in a Special Reconnaissance Report at the GC1QP31 TSG.
