Frank M. Pinkerton (1871-1930), was born in November 1871 at Marshalltown, Iowa, the fifth of seven children, son of Asa Pinkerton (1834-1892), a farmer/gardener, and Anna E. Stewart Pinkerton(1840-1891). His family had lived in Illinois and moved to Marshalltown, Iowa soon before Frank M. Pinkerton was born. His family lived on their farm at 803 Jerome Avenue. He lived his whole life inMarshalltown and never married. After graduating the local school he worked in town as a clerk.

In the December 1904 issue of The Numismatist, page 378 he ran a six-line ad selling coins. In the January 1905 issue of The Numismatist, page 32 he ran the same six-line adselling coins.

He also advertised as a coin dealer in Philatelic West, Vol. 31, No. 1, September (1905). According to Tom Elder Pinkerton was a winning bidder in his September 1905 auction, received his coinsbut never paid. He mentioned this in two issue of the Elder Monthly in 1906.

Thomas Lindsay Elder reported in his Elder Monthly, April (1906)

When there was a problem with the mail not only the buyer but the Post Office was to blame with Tom Elder. Judging from the facts presented by Elder it seems unfair to have condemned Pinkertonbased on the evidence. It may have been a genuine case of mail tampering in which both parties, i.e., Elder and Pinkerton, were victimized. But, Tom Elder, hot-tempered and short-fused could only seehis point of view, neither that of either Pinkerton nor the Post Office officials. When a deal went wrong "everybody was wrong and at fault" in Elder's mind. Although Elder ispugnacious you still can't help liking him and feeling bad for him about this particular case since he was robbed one way or the other.
