For those of you looking to buy Mylar holders for your banknotes:
If you've ordered Mylar holders from SeillitStores (as recommended by R.P.), you may have noticed that they were quite narrow, suitable for American notes but not so much for the wider BofC notes, especially the 1935 and 1937.
However, they made a special order at my request for holders 1/4 inch wider than the standard small size. These are somewhat wider than the ones Brent ordered a while back and are just perfect for the 1935/37 notes with room to spare.
They ordered 1000, of which 500 should still be available. They are quite inexpensive (40 cents or less) and of nice quality (nice straight edges). The dimensions are 6"500 by 3"125.
