Hello All,
I only own a couple old gloves so it is not my area of expertise, however I have been thinking about buying this one and have communicated with the seller several times on it. I know these old crescent gloves are fairly valuable, especially the white ones it appears. I want to be able to make him an offer on it that is fair, can anyone provide insight into it's value? I am not in tune enough to know how much the condition effects it, etc. It looks like there is a split at the top of one of the fingers and that the leather is starting to fray a little in general. The tag and button on back look to be fairly nice. Thoughts? Appreciate the help.
Best,
Jeff
