Pretty sure it's Rockingham, 1800's. The crazing, the kiln marks, and the yellow base clay all lead me to think it's not a reproduction. I have my great-grandmother's bowl like this (but much larger), and the aging and overall appearance on this one matches mine.
Unfortunately, this one has a chip out of the top rim. Otherwise, I'm seeing bowls like this online for anywhere from $50 up to $150 - $175. I paid 50 cents.
I also found a piece of Imperial's "Candlewick" glassware from the 50's, a Couroc bowl from the 60's, a set of 4 Christmas dinner plates (never used - sticker on back), some cute Halloween plates that I'll use at my party next year, a piece of Corningware French White, some Corelle plates with the Shadow Iris pattern, a big mixing bowl from a stand mixer, two 8" pie pans, one 9" deep dish pie pan (giving the pie pans away), and an old Foley aluminum wide-mouthed canning funnel. I paid no more than $1 for any one item in there, and most were 50 - 69 cents.
I usually don't have such luck but yesterday was a good day. Yea!
