It was exactly 6 months ago today that I started my pre 1860 Victorian copper penny collection, and as I've been obsessively scouring dealer's lists, auction sites and e bay on a daily or even twice daily basis since, I thought it might be quite informative to state scarcity of the different varieties as I've experienced them, out of interest.
I've now got almost all the main types, except for 1843 no colon after reg, 1849, 1856 OT and 1860/59.
This is how I've found the Bramah and Peck varieties availability:-
Bramah 2a - 1841 light curved marking to left of foot of 4, an 8 having apparently been commenced there - *one seen, correctly attributed, bought, dealer EF
Bramah 2c - 1841 the upper arm of last F is halfway down upstroke - two seen, one bought, e bay, EF, neither attributed, just offered as date type.
Bramah 3b - 1843 Last E is incomplete having no base stroke or upper serif to up-stroke (DFF) - none seen
Bramah 4b - 1844 as 3b - *one seen, dealer, correctly attributed, bought, F
Medusa 1847 - *one seen offered, not bought.
Bramah 10a/Peck 1494 - 1848/6 - *one seen, bought, dealer, VF . Same dealer had another touted as 1848/6, but magnification showed it clearly wasn't.
Bramah 15/Peck 1503 - 1853 OT last colon slightly nearer F >5 seen, one bought, dealer, EF. Commoner than I expected and only the one I bought was attributed as such, the remainder offered as date type.
1853 plain trident - 3 seen, one bought, dealer, bargain, EF. The other two sub fine on e bay. Not at all easy to get.
Bramah 17a/Peck 1507 - 1854 OT no colons - *one seen and bought, dealer, not quite fine.
Bramah 18a/Peck 1505 - 1854/3, none seen offered for sale. Several touted as 1854/6, but, as I suspected, not the real deal. Much rarer than indicated by either Peck or Bramah.
Bramah 23a - 1857 OT - no serif to the figure 7 in date - none seen, anywhere. Does this variety even exist?
Bramah 24a/Peck 1514 - 1857 PT - date in much smaller figures >5 seen, one bought VF, e bay.
Bramah 25c - 1858 - over/? - *one seen, bought, dealer F
Bramah 26a - 1858 first I is without serifs - 2 seen, one bought, dealer VF, unattributed.
Peck 1517 - 1858 date in smaller figures - *one seen, dealer, bought - doubles up as 8/6
Peck 1520 - 1859 date in smaller figures - >5 seen, one bought, e bay, a/UNC
* one only seen offered in the 6 months from any source, before or since the purchase.
No attempt yet made to collect any pre 1857 varying date sizes, types, width.
