How can you tell if an early coin was struck in a collar?

diameter. looking at the edge. any coin struck w/o a collar aka out of collar will have "smeared" details around the obv/rev legend.

only way i can imagine a coin's diameter not increasing from not having anything around the edge of the dies when the obv/rev press on the flan is if insufficient pressure is applied from the obv/rev dies.

i can't imagine that dies with edges to replace the need for a collar would be able to handle any but the most gentle of pressure, so there would have to be a collar to contain metal being struck.

MAD?

Partial collar/tilted collar

really doesn't look like pmd but could be although a long-shot

It's a complex coin as I understand called Wood 29b and associated with the Canadian Blacksmith Series but also is (was) Low 284. Struck by the Trues in New York State these dies along with the Peck storecard obverse made their way into Canada where these dies disintegrate and are muled with various crude reverses. The die here is cracked much more severely than it's HTT prior use in fact it sits on two levels and is well worn. The reverse has an odd sort of raised rim/lip along with the missing legend. The edges are round. >>>what I'm trying to determine is if this piece is actually Wood 29c which is the Starbuck dies as this, broken like this, on an HTT planchet but struck without a collar,
