Refer to DSS User Guide, Price History, Timeseries Pricing and Single Price History reports provide historical pricing from as far back as 1980.

I have tested with TimeSeriesExtractionRequest and I can get the data before 2013.

The request is:

{
  "ExtractionRequest": {
    "@odata.type": "#ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.TimeSeriesExtractionRequest",
    "ContentFieldNames": [
      "File Code",
      "RIC",
      "Trade Date",
      "Close Price",
      "Alternate Close Price",
      "Split Factor",
      "High Price",
      "Low Price",
      "Open Price",
      "VWAP Price",
      "Turnover",
      "Volume",
      "Bid Price",
      "Asset Type",
      "Quote ID",
      "Bid Yield",
      "Universal Close Price",
      "Exchange Code",
      "Currency Code"          
    ],
    "IdentifierList": {
      "@odata.type": "#ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.InstrumentIdentifierList",  
      "InstrumentIdentifiers": [{
        "Identifier": "AAPL.O",
        "IdentifierType": "Ric"
      }]
    },
    "Condition": {
      "LastPriceOnly": false,
      "StartDate": "2010-05-24T00:00:00.000Z",
      "EndDate": "2012-05-31T00:00:00.000Z"
    }
  }
}

The response is:
