Many of my vintage ties have no maker's label.
Think about the characteristics that apply to your ties, one by one, or perhaps by grouping them.
Earlier ties - 2os - 60s - are generally more valuable than 70s-90s.
Silk is worth more than nylon or poly
Patterns that are bold, or fanciful, or novelty-themed are easier sellers than more neutral ties. If a tie is hand painted, and done well, that's a potential selling point too.
Extremes of width seem to sell better than more middle-of-the-road silhouettes. Super skinny ties have been trendier for the last little while, but some of my customers love neckties that are super wide.
Once you know the keywords that apply your tie groups, go to a vintage selling venue, and see what the price ranges are, keeping in mind that you are looking at asking price not selling price. Hope this helps!
