Stampless Steamship Covers

Anybody have any idea what these are and maybe their value?

Yes, these are examples of steamship mail covers, sent to foreign destinations. The difference between those and ship letters is that the ships here were under contract to the PO, and rates were different from ship letters, (I think) higher for more reliable/regularly scheduled service.

Both probably originated from New York City. The other option was the overland route, transferring to the Canada mails at certain border towns.

The 5c in circle shows what the US would get and (I'm guessing) corrected to the 10c total (Canada got 5c, too). The same rate applied for overland service. 1876 is very late for the N. YORK/STEAMSHIP marking. It's also probably very late for mail that wasn't prepaid.

Great postmark strikes on both covers, but covers are faulty.

Thanks for the information. It is what I suspected but couldn`t put the pieces together. I think the scans are faulty because after 140 years the covers are in great shape! They look much better in person!

These covers were brought into New York on a steamship (likely from the Caribbean) and rated at 5 cents (due) for an incoming steam letter per the rates of July 1, 1875. The covers then went overland, likely by rail, to Canada where the 5 was obliterated and the 10 rate applied.

I've sold a few of these, mostly Havana Cuba. They sold in the range $18-25. I have no idea how much covers addressed to Canada would sell for.
