Good topic. I don’t pay any attention to anyone labeling something “rare.” I typically ignore it. I am one of those who either wants it or not, and if it is rare, and I want it, I will have already defined it as rare or not for myself anyway. I have seen yo-yos I think are rare, but they were not listed as rare. I have seen yo-yos listed as rare but I did not believe they were rare at all. I ignore that word altogether.
As for that “offer up” when someone is looking for money for the item, I find it extremely annoying as well. It seems like people are wasting our time seeking a “yo-yo appraisal,” rather than a sincere willingness to let the thing go. I am sick of “offering up” so someone can appraise their yo-yo. It is the new way to find out what your old yo-yo is currently worth…the old “offer up.” Then, they get a bunch of PMs so they can gauge the value of what they have. There is no intention to sell. I see that and look the other way now. Total waste of time. Anytime I list something, I list a price. I’m not for all the games and beating around the bush.
On the topic of engraved vs. unengraved, I value them equally. I’m more impressed with what the yo-yo is, it’s condition, and how it plays, not whether there is something engraved on it. Some engraving is nice, and some looks awful, so that is a 50/50. I could take it or leave it, so it’s the yo-yo in great condition I’m after. If I bought a Toyota, I know what it is, so if I remove the emblems and logos, I know it’s still a Toyota. The emblems and logos are for other people to know what I have, and the company to advertise, but its not for me. I guess once I know what the thing is, I don’t care how obvious it might be to others. I bought the brand but don’t care if everyone knows it or not. I value them equally and could care less either way.
It is clearly in the rules #13 posted by Yoyoexpert, not to list things on the BST you have no intention of getting rid of. Clear rule violation to do it. But, people do it all the time anyway.
