I know nothing about these strikes & my book has nothing on them.A friend owns them & I'm trying to find out what they are worth for her.Any help will be appreciated.They are as follows:

Two Dollar Motorcycle Series with Black Hills Novelty (All on rim)and picture of cycle with Sturgis 2001 on insert.
The other side has Blackhiils Motorcycle Races & Rally Sturgis,S.D. (All on rim)and on insert is a picture of Mt.Rushmore with Est.1938 above it & a cycle with mint mark G.It seem's to be yellow or gold in total color

Limited Edition Classic Motorcycle Series Sturgis 1997(All on rim)& Cleveland 1929 picture of cycle on insert.The other side say's Historic Deadwood Blackhills SouthDakota(All on rim) with picture of Mount Rushmore and .999 Fine Silver on insert.I don't see any mint mark and the strike seem's to be all silver including the rim.

This is the best description I can give.Hope someone can help me out with these 2 strikes and LMK exactly what they are and what they are worth. Thanks !! Larry SS# 709
