Small problem my friend. You asked about Shield Nickles, which do not have Lady Liberty on either side, and posted pictures of 3¢ cupro-nickle coins, which do. So, which are you asking about? If it's the 3¢ pieces, they are not very valuable in the condition shown, and even in MS grades they are pretty much <$1,000. On the other hand, the Red Book shows shield nickles in both the regular no-mint mark version, and with a repunched date, which might be worth a little more, even in low grades comparable to your pictures.
