<prompt> Human: My grandfather gave me some stock certificates for a company that was bought up by a bigger corporation in 2006 - I was 16 at this time, so I never had a hand in any of this. Ever since then, everything is digital and I thought it was all well, set up as a DRIP.Sometime last year, I started getting letters from the online company that holds? my stock saying that they have become aware of some additional stock certificates for the original company before it was bought out that we never redeemed. The letter says theyll give us 1.35 or 1.65:1 ratio on redemption, but will have to charge a 10 fee to redeem them.I talked to my parents and they were able to find some physical stock certificates, just like they were described but my mom has been dragging her feet on this, and I really dont want to pay the 10 fee I believe the value of these certificates is worth like 6500 after the ratio - how else can I get these redeemed and turned into stock so I can sell them all when I want to buy a house?  <response>: Yeah a 10 fee is pretty high.I would call a few online brokers such as ETrade and Charles Schwab and see what they say. Tell them you can bring in the stock certs and use them to open up an account. Usually the fee for creating or redeeming stock certs is something like 15-25.Some research may be needed but brokerages have information not available to the public, theres something called a Bloomberg Terminal that has information on every company thats ever existed and all of its acquisitions, spin-offs, etc. Your stock should have a unique identifier such as a CUSIP and they should be able to track it down. They wont do this for free but if youre a paying customer they should.
