The 4¢ imperforate, Scott 346, may be faked by trimming the perforations
from any of the 4¢ sheet stamps, although to be double-line
watermarked it would need to be a Scott 334. It is unlikely that the mint stamp would
be faked since the mint perf 12 double-line watermarked stamp actually has a higher catalog value than the
mint imperforate stamp. This is not the case for the used stamps however, and care
must be taken to insure authenticity. Collecting in pairs is always best, although
margin copies or four large margins usually insure authenticity. Remember the
4¢ imperforate stamp must be double-line watermarked to be genuine.
