Kevin,
Your doing the right thing. If you are new to buying signs, surely ask first if you are not sure. Both of these signs you've asked about are repops, and you were questioning, so your being cautious and that is the best way not to get burned. As much as I hate to walk away sometimes, I also would hate to throw away good money on a fake. So stay cautious. Stay patient. The right ones will come along.
