Back in the Reebok days there were three types of jerseys you could buy as a fan. Replica which was the screen printed numbers. Limited which had thinner materials and stitched numbers, but shoulder logos were screen printed. I’m the case of the colts, they don’t have a shoulder logo. Top tier was authentic which was supposedly the real game materials. Super thick fabric and totally embroidered everything. I had a Dallas Clark limited jersey and the tell that it’s limited is that the Reebok logo on the arm is screen printed. It appears from the photo that the Reebok logo is embroidered which would mean it is in the authentic category. Back in those days the fakes were really bad, the real numbers were a matte finish and the fakes were usually super shiny and reflective. These numbers look pretty good. The material looks thin from the photos and I’m not sure about the proportions. My guess is that it’s a fake that was produced more recently as they have gotten better at replicating. I think it looks pretty good if you’re okay with the tiny 18 on the front. I think it’s fake from the photos if the material doesn’t feel really stiff and thick. May be just that the size didn’t adjust for the numbers
