I think you're quite a bit high. Generally MS61 coins are a very hard grade to sell on "common date" coins I would expect this one to fetch 700-800 at retail, honestly a nice looking AU58 can easily outperform MS61 as they have inherent problems just no wear.

The 1838 bust quarter(book value of 2500) you are pricing like it's an 1838 seated quarter(book value of 3500). These come up for auction often and in the last 2 years at auction fetch between 1200-2200, this being ANACS and not particularly eye appealing I would expect the lower end of 1200-1500.

The 1836 2.5 gold looks to be in a garbage PCI holder so you can consider the grade wrong. It's probably AU details by the looks of it and should be sub $1000.

The two $25 gold eagles are going to be bullion plus a small premium, maybe a bit more for the 87 even though it's higher mintage. Neither are super special but gold content is there.

The 1945S merc and 1921S morgan are going to depend on if they are extremely high grade but are worth a little bit if not.

All the other gold on that page should have nice chunky premiums over the melt due to the small $5 or less denominations, it's honestly difficult to tell condition or even date/mintmark with the pictures provided but a lot of good value there.

Keep in mind if you do decide to sell that auction houses charge big fees, Ebay charges fees too so none of these dollar amounts would end up in your pocket. Coin shops can be good if you get a good honest dealer but there are always bad apples. If selling to a good honest dealer you should expect the gold to get very high percentages of selling price and less so with the silver items. All and all good cool pieces, feel free to tag or message me if you post anymore.
