I deposited them with my phone. I have an IRS check about a year old for less than $6.00 still didn't deposit it. Probably expired? Some were Bday and Xmas gifts to my son. I just give him the cash and toss the checks on my desk. Old people still insist on writing checks. Just added them up $2935 nice vacation money. Last time I did this I think they have a per check limit or at least they did like 18 months ago. 1 or two they wouldn't accept with the app. I had 15 checks that time. I ended up taking all those to the bank.
