The word Change doesn't seem to make much sense in this quote from A Christmas Carol. To emphasis the sentence, I kept it in bold-type.
MARLEY was dead, to begin with. There is no doubt whatever about that. The register of his burial was signed by the clergyman, the clerk, the undertaker, & the chief mourner. Scrooge signed it. And Scrooge's name was good upon 'Change, for anything he chose to put his hand to.
