What To do can't use xrp in my wallet

[Johnjohn305]

So I found a old Coinbase wallet of mine and I have over 1000$ worth of xrp on it but I haven't messed with it in so long and the master key is disabled now I have the 12 word phrase but that's about it I mean it's been so long I don't even know how I found that what can I do to access my funds if someone can help I will break you off 300$ or if you know what your doing it's the only crypto on that wallet I can give you the wallet for 300$ if you know for sure you can get it off and save myself the headache cause at this point I forgot about it this long anyway it's not much of a loss to me
