To price an insulator is a difficult thing. Many people will disagree with my prices, but remember, an insulator is only worth what someone will pay for it. I am basing my prices on observations at bottle sales and shows, price lists from different parts of the United States, shops I have visited and insulators I have seen sell at a certain price. Each month I will list certain insulators and prices I feel they should sell for. Of course these prices will refer to mint or near mint insulators, plus you must keep in mind that prices on insulators are much like the stock market--they fluctuate up and down according to the supply and demand. One month they might be high, due to scarcity, and maybe next month a whole line has come down and flooded the market. When these are absorbed into collections, then the price starts rising again. The Maydwell-20 milk glass is a classic example of this. It started out around $30 and went down as low as $4 and now is on the rise again up to $12 or $14. Of course I am speaking for the West coast. Milk glass insulators are considerably higher in the East. Prices fluctuate in different parts of the country, and that's another reason it's so difficult to price them. A few of the insulators that are selling for over $100 are:

Foster Brothers (CD 740)
E C & M Co. SF., Cobalt (CD 123)
California, one piece transposition, SCA (CD 200)
California, one piece transposition, Sage Green (CD 201)
Gregory (CD 159)
Boston Bottle Works (CD 158)
Otis Patent lightning rod insulator
U.S. Tel., Chester N. Y., (CD 735)
E.R.W., unthreaded (CD 736)
Calif. Elec. Works, Cobalt (CD 130.1)
McKee, unthreaded (CD 731)
Tillotson, unthreaded (CD 731)
Seilers (CD 130.2)

That's all for now. There may be a few I missed. That's where you readers can jog my memory. I expect this column to draw some comments, good and bad, so I'll be waiting to hear from you.
