The stock is in my IRA and I was thinking of selling it and paying off my house balance what type of taxes would I be paying today's coast or coast at the time I got the stock and would I pay a10 present penalty I am 53

If you originally received the ESOP shares as a non-taxable event (which is likely), then when you withdraw it from your IRA the entire amount of the withdrawal is taxable - so to answer your question your tax is calculated using today's market value of the stock. You will also be hit with a 10% early withdrawal fee. This is not a good idea.
