This image from Fold has a symbol that I cannot identify, shown circled here:
My transcription reads:
Allowed July 23' 1860 at the rate of $4.00 per month from Febry 1st 1859, Subject to all pay ments made on Certificate No 1137 issued April 11th 1859 ?-$3 50/100 per month. Janison
What is the symbol and what does it mean?
Based on the full record, including prior images in the file, it relates to the prior pension amount being $3.50 which is here being raised to $4.
